The categories tabs provide quick access to the main features of your chartplotter. For example, the Sonar tab
displays the views and screens related to the sonar feature. You can save items you commonly access to the
Pinned category.
TIP: To view the available categories tabs, you may need to click and drag a tab to scroll left or right.
The SmartMode items are geared toward an activity, such as cruising or docking. When a SmartMode button
is selected from the home screen, each display in the station can show unique information. For example, when
Cruising is selected from the home screen, one display can show the navigation chart and another display can
show the radar screen.
When multiple displays are installed on the Garmin Marine Network, you can group them together into a station.
A station enables the displays to work together, instead of as several separate displays. You can customize
the layout of the screens on each display, making each screen different on each display. When you change the
layout of a screen in one display, the changes appear on only that display. When you change the name and
symbol of the layout, those changes appear on all displays in the station, to maintain a consistent appearance.

The Automatic Identification System (AIS) enables you to identify and track other vessels, and alerts you to
area traffic. When connected to an external AIS device, the chartplotter can show some AIS information about
other vessels that are within range, that are equipped with a transponder, and that are actively transmitting AIS
information.
The information reported for each vessel includes the Maritime Mobile Service Identity (MMSI), location, GPS
speed, GPS heading, time that has elapsed since the last position of the vessel was reported, nearest approach,
and time to the nearest approach.
Some chartplotter models also support Blue Force Tracking. Vessels being tracked with Blue Force Tracking are
indicated on the chartplotter with a blue-green color.

AIS Targeting Symbols
Symbol Description
AIS vessel. The vessel is reporting AIS information. The direction in which the triangle is pointing
indicates the direction in which the AIS vessel is moving.
Target is selected.
Target is activated. The target appears larger on the chart. A green line attached to the target
indicates the heading of the target. The MMSI, speed, and direction of the vessel appear beneath the
target, if the details setting has been set to Show. If the AIS transmission from the vessel is lost, a
message banner appears.
Target is lost. A green X indicates that the AIS transmission from the vessel is lost, and the
chartplotter displays a message banner asking whether the vessel should continue to be tracked.
If you discontinue vessel tracking, the lost target symbol disappears from the chart or the 3D chart
view.
Dangerous target in range. The target flashes while an alarm sounds and a message banner
appears. After the alarm has been acknowledged, a solid red triangle with a red line attached to it
indicates the location and the heading of the target. If the safe-zone collision alarm has been set to
Off, the target flashes, but the audible alarm does not sound and the alarm banner does not appear.
If the AIS transmission from the vessel is lost, a message banner appears.
Dangerous target is lost. A red X indicates that the AIS transmission from the vessel is lost, and the
chartplotter displays a message banner asking whether the vessel should continue to be tracked. If
you discontinue vessel tracking, the lost dangerous target symbol disappears from the chart or the

Heading and Projected Course of Activated AIS Targets
When heading and course over ground information are provided by an activated AIS target, the heading of the
target appears on a chart as a solid line attached to the AIS target symbol. A heading line does not appear on a
3D chart view.
The projected course of an activated AIS target appears as a dashed line on a chart or a 3D chart view. The
length of the projected course line is based on the value of the projected heading setting. If an activated AIS
target is not transmitting speed information, or if the vessel is not moving, a projected course line does not
appear. Changes in the speed, course over ground, or rate of turn information transmitted by the vessel can
impact the calculation of the projected course line.
When course over ground, heading, and rate of turn information are provided by an activated AIS target, the
projected course of the target is calculated based on the course over ground and the rate of turn information.
The direction in which the target is turning, which is also based on the rate of turn information, is indicated by
the direction of the barb at the end of the heading line. The length of the barb does not change.
When course over ground and heading information are provided by an activated AIS target, but rate of turn
information is not provided, the projected course of the target is calculated based on the course over ground
information.

Setting the Safe-Zone Collision Alarm
CAUTION
The Beeper setting must be turned on to make alarms audible (Sounds and Display Settings, page171). Failure
to set audible alarms could lead to injury or property damage.
Before you can set a collision alarm, you must connect an AIS device to the same network as a compatible
chartplotter.
The safe-zone collision alarm is used for AIS vessels. When a radar is connected to the same network, you can
also use the safe-zone collision alarm for MARPA targets. The safe zone is used for collision avoidance and can
be customized.
1Select Settings > Alarms > Collision Alarm > On.
A message banner appears and an alarm sounds when an AIS-activated vessel enters the safe-zone area
around your boat. The vessel is also labeled as dangerous on the screen. When the alarm is off, the message
banner and audible alarm are disabled, but the vessel is still labeled as dangerous on the screen.
2Select Range, and select a distance for the safe-zone radius around your vessel.

AIS Aids to Navigation
An AIS aid to navigation (ATON) is any kind of navigational aid that is transmitted over the AIS radio. ATONs are
displayed on the charts and have identifying information, such as position and type.
There are three main kinds of AIS ATONs. Real ATONs physically exist and send their identifying and location
information from their actual location. Synthetic ATONs physically exist, and their identifying and location
information is sent from another location. Virtual ATONs do not actually exist, and their identifying and location
information is sent from another location.
You can view AIS ATONs on the chart when the chartplotter is connected to a compatible AIS radio. To show
AIS ATONs, from a chart, select Options > Layers > Chart > Navaid > ATONs. You can view more information
about an ATON if you select the ATON on the chart.

AIS Distress Signals
Self-contained AIS distress signal devices transmit emergency position reports when activated. The chartplotter
can receive signals from Search and Rescue Transmitters (SART), Emergency Position Indicating Radio
Beacons (EPIRB), and other man overboard signals. Distress signal transmissions are different than standard
AIS transmissions, so they appear differently on the chartplotter. Instead of tracking a distress signal
transmission for collision avoidance, you track a distress signal transmission to locate and assist a vessel
or person.
Navigating to a Distress Signal Transmission
When you receive a distress signal transmission, a distress signal alarm appears.
Select Review > Go To to begin navigation to the transmission.

Supported Maps
To help you have a safe and enjoyable time on the water, Garmin devices only support official maps produced
by Garmin or an approved third party producer.
You can purchase maps from Garmin. If you purchase maps from a seller other than Garmin, investigate the
seller before purchasing. Be extra cautious with online sellers. If you have purchased an unsupported map,
return it to the seller.
Garmin Quickdraw Contours Mapping
WARNING
The Garmin Quickdraw Contours mapping feature allows users to generate maps. Garmin makes no
representations about the accuracy, reliability, completeness or timeliness of the maps generated by third
parties. Any use or reliance on the maps generated by third parties is at your own risk.
The Garmin Quickdraw Contours mapping feature allows you to instantly create maps with contours and depth
labels for any body of water.
When Garmin Quickdraw Contours records data, a colored circle surrounds the vessel icon. This circle
represents the approximate area of the map that is scanned by each pass.
A green circle indicates good depth and GPS position, and a speed under 16km/h (10mph). A yellow circle
indicates good depth and GPS position, and a speed between 16 and 32km/h (10 and 20mph). A red circle
indicates poor depth or GPS position, and a speed above 32km/h (20mph).
You can view Garmin Quickdraw Contours in a combination screen or as a single view on the map.
The amount of saved data depends on the size of your memory card, your sonar source, and the speed of your
boat as you record data. You can record longer when you use a single-beam sonar. It is estimated that you
might be able to record about 1,500hours of data onto a 2GB memory card.
When you record data on a memory card in your chartplotter, the new data is added to your existing Garmin
Quickdraw Contours map, and is saved on the memory card. When you insert a new memory card, the existing
data does not transfer onto the new card.

Garmin Quickdraw Contours Settings
From a chart, select Options > Quickdraw Contours > Settings.
Recording Offset: Sets the distance between the sonar depth and the contour recording depth. If the water
level has changed since your last recording, adjust this setting so the recording depth is the same for both
recordings.
For example, if the last time you recorded had a sonar depth of 3.1m (10.5ft.), and today's sonar depth is
3.6m (12ft.), enter -0.5m (-1.5ft.) for the a Recording Offset value.
User Display Offset: Sets differences in contour depths and depth labels on your own contours maps to
compensate for changes in the water level of a body of water, or for depth errors in recorded maps.
Comm. Display Offset: Sets differences in contour depths and depth labels on the community contours maps to
compensate for changes in the water level of a body of water, or for depth errors in recorded maps.
Survey Coloring: Sets the color of the Garmin Quickdraw Contours display. When this setting is turned on, the
colors indicate the quality of the recording. When this setting is turned off, the contour areas use standard
map colors.
Green indicates good depth and GPS position, and a speed under 16km/h (10mph). Yellow indicates good
depth and GPS position, and a speed between 16 and 32km/h (10 and 20mph). Red indicates poor depth or
GPS position, and a speed above 32km/h (20mph).
Depth Shading: Specifies the minimum and maximum depths of a depth range and a color for that depth range.
Navigation with a Chartplotter
WARNING
All route and navigation lines displayed on the chartplotter are only intended to provide general route guidance
or to identify proper channels, and are not intended to be precisely followed. Always defer to the navaids and
conditions on the water when navigating to avoid groundings or hazards that could result in vessel damage,
personal injury, or death.
The Auto Guidance feature is based on electronic chart information. That data does not ensure obstacle and
bottom clearance. Carefully compare the course to all visual sightings, and avoid any land, shallow water, or
other obstacles that may be in your path.
When using Go To, a direct course and a corrected course may pass over land or shallow water. Use visual
sightings, and steer to avoid land, shallow water, and other dangerous objects.
CAUTION
If your vessel has an autopilot system, a dedicated autopilot control display must be installed at each steering
helm in order to disable the autopilot system.
NOTE: Some chart views are available with premium charts, in some areas.
To navigate, you must choose a destination, set a course or create a route, and follow the course or route. You
can follow the course or the route on the Navigation chart, Fishing chart, Perspective 3D chart view, or Mariner’s
Eye 3D chart view.
You can set and follow a course to a destination using one of three methods: Go To, Route To, or Auto
Guidance.
Go To: Takes you directly to the destination. This is the standard option for navigating to a destination. The
chartplotter creates a straight-line course or navigation line to the destination. The path may run over land
and other obstacles.
Route To: Creates a route from your location to a destination, allowing you to add turns along the way. This
option provides a straight-line course to the destination, but allows you to add turns into the route to avoid
land and other obstacles.
Auto Guidance: Uses the specified information about your vessel and chart data to determine the best path
to your destination. This option is available only when using a compatible premium chart in a compatible
chartplotter. It provides a turn-by-turn navigation path to the destination, avoiding land and other obstacles
(Auto Guidance, page57).
Navigation with a Chartplotter 49
When you are using a compatible autopilot connected to the chartplotter using NMEA 2000, the autopilot
follows the Auto Guidance route.
NOTE: Auto Guidance is available with premium charts, in some areas.
The color of the route line changes depending upon several factors (Route Color Coding, page50).

When using Go To, a direct course and a corrected course may pass over land or shallow water. Use visual
sightings, and steer to avoid land, shallow water, and other dangerous objects.
As you navigate, the color of the route might change to indicate when you should take caution.
Magenta: Default route/course line.
Thin purple: Dynamically corrected course, indicating you are off course.
Orange: Caution! This segment of the route may be near the thresholds of the Auto Guidance depth and height
settings. For example, the route segment is orange when the route crosses under a bridge or is in potentially
shallow waters. Garmin Navionics+ and Garmin Navionics Vision+ charts only.
Red striped: Warning! This segment of the route might be unsafe, based on the Auto Guidance depth and height
settings. For example, the roue segment is red striped when the route crosses under a very low bridge or is in
shallow waters. This line is red striped in Garmin Navionics+ and Garmin Navionics Vision+ charts only; it is
magenta and gray striped in previous versions of the charts.
Gray: Cannot calculate this segment of the route due to land or other obstacles, or there is no chart coverage
area in that location.

Auto Guidance
WARNING
The Auto Guidance feature is based on electronic chart information. That data does not ensure obstacle and
bottom clearance. Carefully compare the course to all visual sightings, and avoid any land, shallow water, or
other obstacles that may be in your path.
All route and navigation lines displayed on the chartplotter are only intended to provide general route guidance
or to identify proper channels, and are not intended to be precisely followed. Always defer to the navaids and
conditions on the water when navigating to avoid groundings or hazards that could result in vessel damage,
personal injury, or death.
NOTE: Auto Guidance is available with premium charts, in some areas.
You can use Auto Guidance to plot the best path to your destination. Auto Guidance uses your chartplotter to

Auto Guidance Path Configurations
CAUTION
The Preferred Depth and Vertical Clearance settings influence how the chartplotter calculates an Auto Guidance
path. If a section of an Auto Guidance path is shallower than the Preferred Depth or lower than the Vertical
Clearance settings, the section of the Auto Guidance path appears as a solid orange line or a red striped line
in Garmin Navionics+ and Garmin Navionics Vision+ charts and appears as a magenta and gray striped line in
previous versions. When your boat enters one of those areas, a warning message appears (Route Color Coding,
page50).
NOTE: Auto Guidance is available with premium charts, in some areas.
NOTE: Not all settings apply to all maps.
You can set the parameters the chartplotter uses when calculating an Auto Guidance path.
Select Settings > Preferences > Navigation > Auto Guidance.
Preferred Depth: Sets the minimum water depth, based on chart depth data, that your boat can safely travel
over.
NOTE: The minimum water depth for the premium charts (made before 2016) is 3 feet. If you enter a value of
less than 3 feet, the charts only use depths of 3 feet for Auto Guidance path calculations.
Vertical Clearance: Sets the minimum height of a bridge or obstacle, based on chart data, that your boat can
safely travel under.
Shoreline Distance: Sets how close to the shore you want the Auto Guidance path to be placed. The path
may move if you change this setting while navigating. The available values for this setting are relative, not
absolute. To ensure that path is placed the appropriate distance from shore, you can assess the placement
of the path using one or more familiar destinations that require navigation through a narrow waterway
(Adjusting the Distance from Shore, page60).
Navigation with a Chartplotter 59
Adjusting the Distance from Shore
The Shoreline Distance setting indicates how close to the shore you want the Auto Guidance line to be placed.
The Auto Guidance line may move if you change this setting while navigating. The available values for the
Shoreline Distance setting are relative, not absolute. To ensure the Auto Guidance line is placed the appropriate
distance from shore, you can assess the placement of the Auto Guidance line using one or more familiar
destinations that require navigation through a narrow waterway.
1Dock your vessel or drop the anchor.
2Select Settings > Preferences > Navigation > Auto Guidance > Shoreline Distance > Normal.
3Select a destination that you have navigated to previously.
4Select Navigate To > Auto Guidance.
5Review the placement of the Auto Guidance line, and determine whether the line safely avoids known
obstacles and the turns enable efficient travel.
6Select an option:
If the placement of the line is satisfactory, select Options > Navigation Options > Stop Navigation, and
proceed to step 10.
If the line is too close to known obstacles, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Far.
If the turns in the line are too wide, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Near.
7If you selected Near or Far in step 6, review the placement of the Auto Guidance line, and determine whether
the line safely avoids known obstacles and the turns enable efficient travel.
Auto Guidance maintains a wide clearance from obstacles in open water, even if you set the Shoreline
Distance setting to Near or Nearest. As a result, the chartplotter may not reposition the Auto Guidance line,
unless the destination selected requires navigation through a narrow waterway.
8Select an option:
If the placement of the line is satisfactory, select Options > Navigation Options > Stop Navigation, and
proceed to step 10.
If the line is too close to known obstacles, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Farthest.
If the turns in the line are too wide, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Nearest.
9If you selected Nearest or Farthest in step 8, review the placement of the Auto Guidance line, and determine
whether the line safely avoids known obstacles and the turns enable efficient travel.
The Auto Guidance path maintains a wide clearance from obstacles in open water, even if you set the
Shoreline Distance setting to Near or Nearest. As a result, the chartplotter may not reposition the Auto
Guidance line, unless the destination selected requires navigation through a narrow waterway.
10 Repeat steps 3 through 9 at least once more, using a different destination each time, until you are familiar
with the functionality of the Shoreline Distance setting.

Setting the Vessel Type for Sailing Features
You must select a sailing vessel type to use the sailing features.
1Select Settings > My Vessel > Vessel Type.
2Select Sailboat or Sailing Catamaran.
Sail Racing
You can use the device to increase the likelihood that your boat will cross the start line of a race exactly when
the race begins. When you synchronize the race timer with the official race countdown timer, you are alerted
at one-minute intervals as the race start approaches. When you combine the race timer with the virtual start
line, the device measures your speed, bearing, and remaining time on the countdown timer. The device uses this
data to indicate whether your boat will cross the start line before, after, or at the correct time to start the race.
Starting Line Guidance
Sailing start line guidance is a visual representation of the information you need to cross the start line at the
optimal time and speed.
After you set the starboard and port start line pins, and the target speed and time, and after you start the race
timer, a predictor line appears. The predictor line extends from your current location toward the start line and
the laylines that extend from each pin.
The end point and color of the predictor line indicate where the boat will be when the timer expires, based on
your current boat speed.
When the end point is before the start line, the line is white. This indicates the boat must increase speed to
reach the start line on time.
When the end point is past the start line, the line is red. This indicates the boat must reduce speed to avoid a
penalty for reaching the start line before the timer expires.
When the end point is on the start line, the line is white. This indicates the boat is moving at an optimal speed to
reach the start line when the timer expires.
By default, the start line guidance window and the race timer window appear in the Sail Racing combination
screen.
Setting the Starting Line
The start line guidance window is added to the Sail Racing combination screen by default.

Sonar Fishfinder
When properly connected to a transducer, your compatible chartplotter can be used as a fishfinder. Chartplotter
models without an xsv or xs in their names require a Garmin sounder module and transducer to display sonar
information.
For more information about which transducer is best for your needs, go to garmin.com/transducers.
Different sonar views can help you view the fish in the area. The sonar views available vary depending on
the type of transducer and sounder module connected to the chartplotter. For example, you can view certain
Panoptix sonar screens only if you have a compatible Panoptix transducer connected.
There are four basic styles of sonar views available: a full-screen view, a split-screen view that combines two
or more views, a split-zoom view, and a split-frequency view that displays two different frequencies. You can
customize the settings for each view in the screen. For example, if you are viewing the split-frequency view, you
can separately adjust the gain for each frequency.
If you do not see an arrangement of sonar views to suit your needs, you can create a custom combination
screen (Creating a New Combination Page, page15). You can also add sonar views to SmartMode layouts
(Adding a SmartMode Layout, page16).

one GPSMAP 8417 device mounted at the back of the boat, you can view the sonar data from another GPSMAP
device and Garmin ClearVü transducer mounted at the front of your boat.
When sharing sonar data, the values of some sonar settings, such as Range and Gain, are synchronized across
the devices on the network. The values of other sonar settings, such as the Appearance settings, are not
synchronized and should be configured on each individual device. In addition, the scroll rates of the various
traditional and Garmin ClearVü sonar views are synchronized to make the split views more cohesive.
NOTE: Using multiple transducers simultaneously can create cross talk, which can be removed by adjusting the
Interference sonar setting.

Adjusting the Level of Detail
You can control the level of detail and noise shown on the sonar screen either by adjusting the gain for
traditional transducers or by adjusting the brightness for Garmin ClearVü transducers.
If you want to see the highest intensity signal returns on the screen, you can lower the gain or brightness to
remove lower intensity returns and noise. If you want to see all return information, you can increase the gain or
brightness to see more information on the screen. This also increases noise, and can make it more difficult to
recognize actual returns.
1From a sonar view, select Options.
2Select Gain or Brightness.
3Select an option:
To increase or decrease the gain or brightness manually, select Up or Down.
To allow the chartplotter to adjust the gain or brightness automatically, select an automatic option.

Adjusting the Color Intensity
You can adjust the intensity of colors and highlight areas of interest on the sonar screen by adjusting the color
gain for traditional transducers or the contrast for some transducers. This setting works best after you have
adjusted the level of detail shown on the screen using the gain or brightness settings.
If you want to highlight smaller fish targets or create a higher intensity display of a target, you can increase
the color gain or contrast setting. This causes a loss in the differentiation of the high intensity returns at the
bottom. If you want to reduce the intensity of the return, you can reduce the color gain or contrast.

To cancel the zoom, deselect the Zoom option.
Setting the Scroll Speed
You can set the rate at which the sonar image moves across the screen. A higher scroll speed shows more
detail until there is no additional detail to show, at which point it starts stretching out the existing detail. This
can be useful while moving or trolling, or when you are in very deep water where the sonar is pinging very slowly.
A lower scroll speed displays sonar information on the screen longer.
For most situations, the Default setting provides a good balance between a quickly scrolling image and less
distorted targets.
1From a sonar view, select Options > Sonar Setup > Scroll Speed.
2Select an option:
To adjust the scroll speed automatically using speed-over-ground or water speed data, select Auto.
The Auto setting selects a scroll rate to match the boat speed, so targets in the water are drawn with
the correct aspect ratio and appear less distorted. When viewing Garmin ClearVü/SideVü sonar views or
searching for structure, it is recommend to use the Auto setting.
To scroll faster, select Up.
To scroll more slowly, select Down.
Adjusting the Range
You can adjust the range of the depth scale for traditional and Garmin ClearVü sonar views. You can adjust the
range of the width scale for the SideVü sonar view.
Allowing the device to adjust the range automatically keeps the bottom within the lower or outer third of the
sonar screen, and can be useful for tracking a bottom that has minimal or moderate terrain changes.
Manually adjusting the range enables you to view a specified range, which can be useful for tracking a bottom
that has large terrain changes, such as a drop-offs or cliffs. The bottom can appear on the screen as long as it
appears within the range you have set.
1From a sonar view, select Options > Range.
2Select an option:

86 Sonar Fishfinder
Sonar Noise Rejection Settings
From a sonar view, select Options > Sonar Setup > Noise Reject.
Interference: Adjusts the sensitivity to reduce the effects of interference from nearby sources of noise.
The lowest interference setting that achieves the desired improvement should be used to remove
interference from the screen. Correcting installation issues that cause noise is the best way to eliminate
interference.
Color Limit: Hides part of the color palette to help eliminate fields of weak clutter.
By setting the color limit to the color of the undesired returns, you can eliminate the display of undesired
returns on the screen.
Smoothing: Removes noise that is not part of a normal sonar return, and adjusts the appearance of returns,
such as the bottom.
When smoothing is set to high, more of the low-level noise remains than when using the interference control,
but the noise is more subdued because of averaging. Smoothing can remove speckle from the bottom.
Smoothing and interference work well together to eliminate low-level noise. You can adjust the interference
and smoothing settings incrementally to remove undesirable noise from the display.
Surface Noise: Hides surface noise to help reduce clutter. Wider beam widths (lower frequencies) can show
more targets, but can generate more surface noise.
TVG: Adjusts the time varying gain, which can reduce noise.
This control is best used for situations when you want to control and suppress clutter or noise near the water
surface. It also allows for the display of targets near the surface that are otherwise hidden or masked by
surface noise.
Sonar Appearance Settings
From a sonar view, select Options > Sonar Setup > Appearance.
Color Scheme: Sets the color scheme.
Color Gain: Adjusts the intensity of colors (Adjusting the Color Intensity, page85).
A-Scope: Displays a vertical flasher along the right side of the screen that shows instantaneously the range to
targets along a scale.
Depth Line: Shows a quick-reference depth line.
Edge: Highlights the strongest signal from the bottom to help define the hardness or softness of the signal.
View Selection: Sets the direction of the Garmin SideVü sonar view.
Fish Symbols: Sets how the sonar interprets suspended targets.
Shows suspended targets as symbols and background sonar information.
Shows suspended targets as symbols with target depth information and background sonar informa
tion.
Shows suspended targets as symbols.
Shows suspended targets as symbols with target depth information.
Pic. Advance: Allows the sonar picture to advance faster by drawing more than one column of data on
the screen for each column of sounder data received. This is especially helpful when you are using the
sounder in deep water, because the sonar signal takes longer to travel to the water bottom and back to the
transducer.
The 1/1 setting draws one column of information on the screen per sounder return. The 2/1 setting draws
two columns of information on the screen per sounder return, and so on for the 4/1 and 8/1 settings.
Echo Stretch: Adjusts the size of the echoes on the screen to make it easier to see separate returns on the
screen.
Sonar Fishfinder 87
When targets are difficult to see , echo stretch makes the target returns more pronounced and easier to
see on the screen. If the echo stretch value is too high, the targets blend together. If the value is too low ,
the targets are small and more difficult to see.
You can use echo stretch and filter width together to obtain the preferable resolution and noise reduction.
With echo stretch and filter width set to low, the display has the highest resolution, but is the most
susceptible to noise. With echo stretch set to high and filter width set to low, the display has a lower
resolution, but has wider targets. With echo stretch and filter width set to high, the display has the lowest
resolution, but is the least susceptible to noise. It is not recommended to set echo stretch to low and filter
width to high.
Overlay Data: Sets the data shown on the sonar screen.
Sonar Alarms
WARNING
The sonar alarms feature is a tool for situational awareness only and may not prevent grounding in all
circumstances. It is your obligation to ensure safe operation of the vessel.
CAUTION
The Beeper setting must be turned on to make alarms audible (Sounds and Display Settings, page171). Failure
to set audible alarms could lead to injury or property damage.
NOTE: Not all options are available on all transducers.
From an applicable sonar view, select Options > Sonar Setup > Alarms.
You can also open the sonar alarms by selecting Settings > Alarms > Sonar.
Shallow Water: Sets an alarm to sound when the depth is less than the specified value.
Deep Water: Sets an alarm to sound when the depth is greater than the specified value.
FrontVü Alarm: Sets an alarm to sound when the depth in front of the vessel is less than the specified value,
which can help you avoid running aground (Setting the FrontVü Depth Alarm, page93). This alarm is
available only with Panoptix FrontVü transducers.
Water Temp.: Sets an alarm to sound when the transducer reports a temperature that is 2°F (1.1°C) above or
below the specified temperature.
Contour: Sets an alarm to sound when the transducer detects a suspended target within the specified depth
from the surface of the water and from the bottom.
Fish: Sets an alarm to sound when the device detects a suspended target.

Advanced Sonar Settings
From a Traditional sonar view, select Options > Sonar Setup > Advanced.
Shift: Allows you to set the depth range on which the sonar is focused. This allows you to zoom in a higher
resolution in the focused depth.
When using shift, bottom tracking may not work effectively, because the sonar looks for data within the depth
range of the focused area, which may not include the bottom. Using shift also can impact the scroll speed,
because data outside the depth range of the focused area is not processed, which reduces the time required
to receive and display the data. You can zoom in to the focused area, which enables you to evaluate target
returns more closely at a higher resolution than just zooming alone.
Btm. Srch. Limit: Limits the search for the bottom to the depth selected when the Range setting is set to Auto.
To minimize the length of time it takes to find the bottom, you can select a depth to limit the search for the
bottom. The device will not search for the bottom deeper than the selected depth.
Transducer Installation Settings
These settings apply to the following types of sonar.
Traditional
Garmin ClearVü
Garmin SideVü
From an applicable sonar view, select an option.
From a Traditional sonar view, select Options > Sonar Setup > Installation.
From a Garmin ClearVü sonar view, select Options > ClearVü Setup > Installation.
From a Garmin SideVü sonar view, select Options > SideVü Setup > Installation.
Transmit Rate: Sets the length of time between sonar pings. Increasing the transmit rate increases the scroll
speed, but it may also increase self-interference.
Reducing the transmit rate increases the spacing between transmit pulses and can resolve self-interference.
This option is available on the Traditional sonar view only.
Transmit Power: Reduces transducer ringing near the surface. A lower transmit power value reduces transducer
ringing, but can also reduce the strength of the returns. This option is available on the Traditional sonar view
only.
Filter Width: Defines the edges of the target. A shorter filter more clearly defines the edges of the targets but
may allow more noise. A longer filter creates softer target edges and may also reduce noise. This option is
available on the Traditional sonar view only.
Flip Left/Right: Switches the SideVü view orientation from left to right. This option is available on the SideVü
sonar view only.
Restore Sonar Defaults: Restores the sonar settings to the factory default values.
Transducers: Allows you to change the transducer, view details about the transducers, and save details to a
memory card.
Sonar Fishfinder 89
Sonar Frequencies
NOTE: The frequencies available depend on the transducers being used.
Adjusting the frequency helps adapt the sonar for your particular goals and the present depth of the water.
Higher frequencies use narrow beam widths, and are better for high-speed operation and rough sea conditions.
Bottom definition and thermocline definition can be better when using a higher frequency.
Lower frequencies use wider beam widths, which can let the fisherman see more targets, but could also
generate more surface noise and reduce bottom signal continuity during rough sea conditions. Wider beam
widths generate larger arches for fish target returns, making them ideal for locating fish. Wider beam widths
also perform better in deep water, because the lower frequency has better deep water penetration.
CHIRP frequencies allow you to sweep each pulse through a range of frequencies, resulting in better target
separation in deep water. CHIRP can be used to distinctly identify targets, like individual fish in a school, and
for deep water applications. CHIRP generally performs better than single frequency applications. Because some
fish targets may show up better using a fixed frequency, you should consider your goals and water conditions
when using CHIRP frequencies.
Some transducers also provide the ability to customize preset frequencies for each transducer element, which
enables you to change the frequency quickly using the presets as the water and your goals change.
Viewing two frequencies concurrently using the split-frequency view allows you to see deeper with the lower
frequency return and, at the same time, see more detail from the higher frequency return.
NOTICE
Always be aware of local regulations on sonar frequencies. For example, to protect orca whale pods, you might
be prohibited from using frequencies between 50 to 80khz within 1/2 mile of an orca whale pod. It is your
responsibility to use the device in compliance with all applicable laws and ordinances.
Selecting the Transducer Frequency

views.
1Measure the horizontal distance from the transducer to the bow.
2From an applicable sonar view, select Options > Sonar Setup > Installation > Bow Offset.
3Enter the distance measured, and select Done.
On the applicable sonar view, the forward range shifts by the distance you entered.
Calibrating the Compass
Before you can calibrate the compass, the transducer must be installed far enough away from the trolling motor
to avoid magnetic interference, and deployed in the water. Calibration must be of sufficient quality to enable the
internal compass.
NOTE: The compass may not work if you mount the transducer on the motor.
NOTE: For best results, you should use a heading sensor such as the SteadyCast heading sensor. The heading
sensor shows the direction the transducer is pointing relative to the boat.
NOTE: Compass calibration is available only for transducers with an internal compass, such as the PS21-TR
transducer.
You can begin turning your boat before calibrating, but you must fully rotate your boat 1.5 times during

Radar
WARNING
The marine radar transmits microwave energy that has the potential to be harmful to humans and animals.
Before beginning radar transmission, verify that the area around the radar is clear. The radar transmits a beam
approximately 12° above and below a line extending horizontally from the center of the radar.
To avoid possible personal injury, do not look directly at the antenna at close range when the radar is
transmitting. Eyes are the most sensitive part of the body to electromagnetic energy.
When you connect your compatible chartplotter to an optional Garmin marine radar, such as a GMR Fantom 6
radar or a GMR 24 xHD, you can view more information about your surroundings.
The radar transmits a narrow beam of microwave energy as it rotates to a 360° pattern. When the transmitted
energy contacts a target, some of that energy is reflected back to the radar.
Radar Interpretation
Reading and interpreting the radar display takes practice. The more you use the radar, the better you will
become at relying on the radar display when you really need it.
Radar can be useful in many situations, such as avoiding collisions when you have limited visibility, for example
when it is dark or foggy, tracking weather, seeing what is ahead of you, and locating birds and fish.
The radar overlay feature can help you interpret the radar display more easily, because it overlays the radar
returns on top of the chart. This can help you identify the difference between a radar return of a land mass,
bridge, or rain cloud. Showing the AIS vessels on the radar overlay can also help you identify features on the
radar display.
In the screenshot below, the radar overlay is turned on. This screen also shows a video feed. We can easily
identify a few items on the radar screen.

Radar Overlay
When you connect your chartplotter to an optional Garmin marine radar, you can use overlay radar information
on the Navigation chart or on the Fishing chart.
Data appears on the radar overlay based on the most recently used radar mode and all settings configurations
applied to the radar overlay are also applied to the last-used radar mode.
98 Radar
Radar Overlay and Chart Data Alignment
When using the Radar overlay, the chartplotter aligns radar data with chart data based on the boat heading,
which is based by default on data from a magnetic heading sensor connected using a NMEA 0183 or NMEA
2000 network. If a heading sensor is not available, the boat heading is based on GPS tracking data.
GPS tracking data indicates the direction in which the boat is moving, not the direction in which the boat
is pointing. If the boat is drifting backward or sideways due to a current or wind, the Radar overlay may
not perfectly align with the chart data. This situation should be avoided by using boat-heading data from an
electronic compass.
If the boat heading is based on data from a magnetic heading sensor or an automatic pilot, the heading data
could be compromised due to incorrect setup, mechanical malfunction, magnetic interference, or other factors.
If the heading data is compromised, the Radar overlay may not align perfectly with the chart data.
Transmitting Radar Signals
NOTE: As a safety feature, the radar enters standby mode after it warms up. This gives you an opportunity to
verify the area around the radar is clear before beginning radar transmission.
1With the chartplotter off, connect your radar as described in the radar installation instructions.
2Turn on the chartplotter.
If necessary, the radar warms up and a countdown alerts you when the radar is ready.
3Select Radar.
4Select a radar mode.
A countdown message appears while the radar is starting up.
5Select Options > Transmit Radar.
Stopping the Transmission of Radar Signals
From a radar screen, select Options > Radar To Standby.
TIP: Press > Radar To Standby from any screen to quickly stop radar transmission.

4Select Done.
5If necessary, repeat for the second zone.
Radar 99
Adjusting the Radar Range
The range of the radar signal indicates the length of the pulsed signal transmitted and received by the radar.
As the range increases, the radar transmits longer pulses in order to reach distant targets. Closer targets,
especially rain and waves, also reflect the longer pulses, which can add noise to the Radar screen. Viewing
information about longer-range targets can also decrease the amount of space available on the Radar screen
for viewing information about shorter-range targets.
Select to decrease the range.
Select to increase the range.
Tips for Selecting a Radar Range
Determine what information you need to see on the Radar screen.
For example, do you need information about nearby weather conditions or targets and traffic, or are you more
concerned about distant weather conditions?
Assess the environmental conditions where the radar is being used.
Especially in inclement weather, longer-range radar signals can increase the clutter on the Radar screen and
make it more difficult to view information about shorter-range targets. In rain, shorter-range radar signals can
enable you to view information about nearby objects more effectively, if the rain clutter setting is configured
optimally.
Select the shortest effective range, given your reason for using radar and the present environmental
conditions.
MotionScope Doppler Radar Technology
The GMR Fantom radar uses the Doppler effect to detect and highlight moving targets to help you avoid
potential collisions, find flocks of birds, and track weather formations. The Doppler effect is the frequency shift
in the radar echo due to the relative motion of the target. This allows for instant detection of any targets moving
toward or away from the radar.
The MotionScope feature highlights the moving targets on the radar display so you can navigate around other
boats or severe weather, or toward fishing spots where birds are feeding at the surface.
The moving targets are color-coded so you can tell at a glance which targets are moving toward or away from
you. On most color schemes, green indicates the target is moving away from you and red indicates the target is
moving toward you.
On some models, you can also adjust the M-Scope Sensitivity setting to change the speed threshold for target
highlighting. A higher setting highlights slower targets, and a lower setting highlights only faster targets.
Enabling a Guard Zone
You can enable a guard zone to alert you when anything comes within a specified area around your boat.
From a radar screen, select Options > Radar Options > Guard Zone.

MARPA
WARNING
This feature is intended to enhance situational awareness and may not prevent collisions in all circumstances.
You are responsible for the safe and prudent operation of your vessel and for remaining aware of obstacles or
hazards in or around the water. Failure to do so could result in an accident causing property damage, serious
personal injury, or death.
Mini-automatic radar plotting aid (MARPA) enables you to identify and track targets and is primarily used for
collision avoidance. To use MARPA, you assign a MARPA tag to a target. The radar system automatically tracks
the tagged object and provides you with information about the object, including the range, bearing, speed, GPS
heading, nearest approach, and time to nearest approach. MARPA indicates the status of each tagged object
(acquiring, lost, tracking, or dangerous), and the chartplotter can sound a collision alarm if the object enters your
safe zone.
Before you can use MARPA, you must have a heading sensor connected and an active GPS signal. The heading
sensor must provide the NMEA 2000 parameter group number (PGN) 127250 or the NMEA 0183 HDM or HDG
output sentence.

Autopilot
WARNING
You can use the autopilot feature only at a station installed next to a helm, throttle, and helm control device.
You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your
capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid
navigational hazards and never leave the helm unattended.
Always be prepared to promptly regain manual control of your boat.
Learn to operate the autopilot on calm and hazard-free open water.
Use caution when operating the autopilot near hazards in the water, such as docks, pilings, and other boats.
The autopilot system continuously adjusts the steering of your boat to maintain a constant heading (heading
hold). The system also allows manual steering and several modes of automatic-steering functions and patterns.
When the chartplotter is connected to a compatible Garmin autopilot system, you can engage and control the
autopilot from the chartplotter. For information about compatible Garmin autopilot systems, go to garmin.com.
When the chartplotter is connected to a compatible Yamaha® autopilot system, you can control the autopilot
from the chartplotter using the Yamaha autopilot screen and overlay bar (Yamaha Autopilot, page115). For
information about compatible Yamaha autopilot systems, contact your Yamaha dealer.
Autopilot Configuration
NOTICE
To avoid damage to your boat, the autopilot system should be installed and configured by a qualified marine
installer. Specific knowledge of marine steering and electrical systems is required for proper installation and
configuration.
The autopilot system must be configured to work properly with your boat. You can configure the autopilot using
a chartplotter on the same NMEA 2000 network as the autopilot. For configuration instructions, go to support
.garmin.com, and download the configuration guide for your specific autopilot model.
Selecting the Preferred Heading Source
NOTICE
For best results, use the autopilot CCU internal compass for the heading source. Using a third-party GPS
compass can cause the data to be delivered erratically and may result in excessive delays. The autopilot needs
timely information, and therefore cannot often use third-party GPS compass data for GPS location or speed.
If a third-party GPS compass is used, the autopilot will likely report loss of navigation data and speed source
periodically.
If you have more than one heading source on the network, you can select a your preferred source. The source
could be a compatible GPS compass or a magnetic heading sensor.
1From the autopilot screen, select Options > Autopilot Setup > Preferred Sources

Automatic Volume Adjustment Based on Speed
If your stereo is connected to a NMEA 2000 network with a device that provides speed information such as an
engine, chartplotter, GPS antenna, water speed sensor, or wind speed sensor, you can set the stereo to adjust
the volume automatically based on the selected speed source (Enabling Automatic Volume Adjustment Based
on Speed, page146).
For example, if a chartplotter with an internal GPS antenna or a stand-alone GPS antenna is on the same NMEA
2000 network as the stereo and you set the Speed Source to Speed Over Ground, the volume increases as your
speed increases.
NOTE: When the volume increases to adjust for speed, the actual volume output changes, but the volume-level
indicator bar and number stays the same.
For more information about connecting the stereo to a NMEA 2000 network, see the installation instructions for
your stereo.
Enabling Automatic Volume Adjustment Based on Speed
1From the Media screen, select Options > Installation.
2Select the name of the stereo.

Stereo Zones and Groups
NOTE: The Zones button appears only for stereos that support multiple speaker zones.
NOTE: The Groups option appears only when you have multiple Fusion stereos connected to one another using
Fusion PartyBus networking.
If a connected stereo is set up to support multiple speaker zones, you can control the audio of the zones
individually from the media screen on the chartplotter. For example, you could make the audio quieter in the
cabin and louder on the deck (Adjusting the Zone Volume, page147).
If you have multiple Fusion stereos connected to one another using Fusion PartyBus networking, you can create
stereo groups and control the networked stereos and groups using the chartplotter.
Depending on the capabilities of the stereo or stereos connected to the chartplotter, you may have multiple
options for controlling zone audio:
For third-party stereos and stereos using Fusion-Link technology, the Local Zones tab allow you to adjust the
volume for all of the enabled speaker zones on the connected stereo.
For multiple Fusion stereos connected to one another using Fusion PartyBus networking, the Group Zones
tab allows you to adjust the volume for any zones on a stereo in the same group as Home Zone.
For multiple Fusion stereos connected to one another using Fusion PartyBus networking, the Network tab
allows you to adjust the volume for any zone on any stereo connected to the Fusion PartyBus network.
146 Media Player
Selecting the Home Zone
If you have multiple stereos connected to the chartplotter, or have a stereo or stereos with multiple speaker
zones connected to the chartplotter, you must designate one speaker zone on one stereo as the home zone.
The playback and volume controls on the media screen adjust only the stereo or zone set as the home zone.
The playback information on the media screen shows the source playing on the Home Zone stereo.
It is recommended to set the home zone as the zone closest to the chartplotter.
NOTE: Some stereos may feature a global zone. Setting a global zone as the home zone allows the controls on
the media page to affect all of the zones on a stereo or media device.
NOTE: The Zones button only appears for stereos or media devices that support multiple media zones.

2Select the name of an existing group.
3Select the stereos you want to add to or remove from the group.
4Select Done.
Group Synchronization
By default, groups you create are not maintained when you turn off stereos in the group. If you turn off a single
stereo added to the group, it leaves the group. If you turn off the primary stereo in the group, the group is
dissolved. You can enable group synchronization to preserve group membership for a stereo after turning it off.
Group synchronization behaves differently based on how you turn the stereos off and on.
If you turn a synchronized stereo off and on by using either the power button on the stereo or a physical
switch on the ignition wire (the red wire), all of the synchronized stereos in the group turn off and on together.
This applies to all of the synchronized stereos in the group, whether or not a stereo is the primary stereo in
the group.
NOTE: Selecting ALL OFF from the power menu on a stereo turns off all stereos on the network, even if they
are not in a group or have group synchronization enabled.
If you turn a synchronized stereo off and on using a physical switch on the power wire (the yellow wire), the
other synchronized stereos in the group behave differently:
If the synchronized stereo is the primary stereo in the group and you turn it off using a physical switch on
the power wire, the other synchronized stereos in the group remain on, but leave the group. When you turn
the primary stereo back on again, the other synchronized stereos rejoin the group.
If the synchronized stereo is not the primary stereo in the group and you turn it off and on using a physical
switch on the power wire, all of the other synchronized stereos in the group remain on and grouped, and
the stereo rejoins the group when you turn it on again.
Enabling Group Synchronization
You must remove the stereo from an existing group before you can enable the Save Group setting. You cannot
update settings when a stereo is part of a group.
You must enable this setting on each stereo that you want to retain group settings after a power cycle.
1From the Media screen, select Options > Installation.
2Select the name of the stereo.
3Select Power Options > Save Group.

distance from shore, you can assess the placement of the Auto Guidance line using one or more familiar
destinations that require navigation through a narrow waterway.
1Dock your vessel or drop the anchor.
2Select Settings > Preferences > Navigation > Auto Guidance > Shoreline Distance > Normal.
3Select a destination that you have navigated to previously.
4Select Navigate To > Auto Guidance.
5Review the placement of the Auto Guidance line, and determine whether the line safely avoids known
obstacles and the turns enable efficient travel.
6Select an option:
If the placement of the line is satisfactory, select Options > Navigation Options > Stop Navigation, and
proceed to step 10.
If the line is too close to known obstacles, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Far.
If the turns in the line are too wide, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Near.
7If you selected Near or Far in step 6, review the placement of the Auto Guidance line, and determine whether
the line safely avoids known obstacles and the turns enable efficient travel.
Auto Guidance maintains a wide clearance from obstacles in open water, even if you set the Shoreline
Distance setting to Near or Nearest. As a result, the chartplotter may not reposition the Auto Guidance line,
unless the destination selected requires navigation through a narrow waterway.
8Select an option:
If the placement of the line is satisfactory, select Options > Navigation Options > Stop Navigation, and
proceed to step 10.
If the line is too close to known obstacles, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Farthest.
If the turns in the line are too wide, select Settings > Preferences > Navigation > Auto Guidance >
Shoreline Distance > Nearest.
9If you selected Nearest or Farthest in step 8, review the placement of the Auto Guidance line, and determine
whether the line safely avoids known obstacles and the turns enable efficient travel.
The Auto Guidance path maintains a wide clearance from obstacles in open water, even if you set the
Shoreline Distance setting to Near or Nearest. As a result, the chartplotter may not reposition the Auto
Guidance line, unless the destination selected requires navigation through a narrow waterway.
10 Repeat steps 3 through 9 at least once more, using a different destination each time, until you are familiar
with the functionality of the Shoreline Distance setting.

Troubleshooting
My device will not acquire GPS signals
If the device is not acquiring satellite signals, there could be a few causes. If the device has moved a large
distance since the last time it has acquired satellites or has been turned off for longer than a few weeks or
months, the device may not be able to acquire the satellites correctly.
Ensure the device is using the latest software. If not, update the device software (Software Updates,
page188).
If the device is using an internal GPS antenna, make sure the device has a clear view of the sky so the internal
antenna can receive the GPS signal. If it is mounted inside of a cabin, it should be close to a window so it can
receive the GPS signal. If the device is mounted inside a cabin and cannot be placed in a location where the
device can acquire satellites, use an external GPS antenna.
If the device is using an external GPS antenna, make sure the antenna is connected to the chartplotter or the
NMEA network. If necessary, see the GPS antenna installation instructions for connection information and
diagrams.
If the device is using an external GPS antenna connected using the NMEA 2000 network, select Settings >
Communications > NMEA 2000 Setup > Device List. Make sure the antenna appears on this list. If it does
not, verify the antenna installation and the NMEA 2000 network installation.
If the device has more than one GPS antenna source, select a different source (Selecting the GPS Source,
page10).
Appendix 193
My device will not turn on or keeps turning off
Devices erratically turning off or not turning on could indicate an issue with the power supplied to the device.
Check these items to attempt to troubleshoot the cause of the power issue.
Make sure the power source is generating power.
You can check this several ways. For example, you can check whether other devices powered by the source
are functioning.
Check the fuse in the power cable.
The fuse should be located in a holder that is part of the red wire of the power cable. Check that the proper
size fuse is installed. Refer to the label on the cable or the installation instructions for the exact fuse size
needed. Check the fuse to make sure there is still a connection inside of the fuse. You can test the fuse using
a multimeter. If the fuse is good, the multimeter reads 0ohm.
Check to make sure the device is receiving at least 12Vdc.
To check the voltage, measure the female power and ground sockets of the power cable for DC voltage. If the
voltage is less than 12Vdc, the device will not turn on.
If the device is receiving enough power but does not turn on, contact Garmin product support.
My device is not creating waypoints in the correct location
You can manually enter a waypoint location to transfer and share data from one device to the next. If you have
manually entered a waypoint using coordinates, and the location of the point does not appear where the point
should be, the map datum and position format of the device may not match the map datum and position format
originally used to mark the waypoint.
Position format is the way in which the GPS receiver's position appears on the screen. This is commonly
displayed as latitude/longitude in degrees and minutes, with options for degrees, minutes and second, degrees
only, or one of several grid formats.
Map datum is a math model which depicts a part of the surface of the earth. Latitude and longitude lines on a
paper map are referenced to a specific map datum.
1Find out which map datum and position format was used when the original waypoint was created.
If the original waypoint was taken from a map, there should be a legend on the map that lists the map datum
and position format used to create that map. Most often this is found near the map key.
2Select Settings > Preferences > Units.
3Select the correct map datum and position format settings.
4Create the waypoint again.
