publication. Thales Navigation licenses* topographical maps, roadmaps, marine charts and points of interest data from
commercial and governmental cartographic sources that provide raw map data. Thales Navigation processes and compresses
the raw data into a format that makes it presentable and manageable to work on our GPS devices. And to ensure that our
map data is as robust as possible, data from multiple sources are often combined to provide a better user experience for our
customers. This processing does not alter the landforms, coordinates or other spatial data that comes in the raw data. The
accuracy of the maps is fundamentally dependent on the source data used to create them. Map data changes frequently due
to both natural and man-made causes. As a result, governmental and commercial cartography companies must continuously
review correct and improve upon their map data. We release new versions of our maps on a regular basis to reflect these
changes.
After processing the data, we test the compatibility of the map with our GPS devices to ensure that the products we release
work properly on our GPS devices. We also beta test our products to get customer feedback prior to release.
2.3.2 GPS Maps and Your Safety
Remember, your GPS device is an aid to navigation. It must be used with common sense and it is important that users
interpret GPS map data with a critical eye. Landscapes and roads change or may be impassable, trees and tall buildings can
obscure GPS signals and your GPS device may not always reflect the complete picture. When using GPS, you must combine
the information provided by your GPS map with your relevant local knowledge, road signage, buoys, depth soundings and
changing local conditions to generate a complete understanding of your situation.
It is your responsibility to ensure compliance to all traffic laws, including pedestrian observance of crosswalks, and to use
good judgment while operating the Magellan GPS receiver. Safety must be your primary concern. The Magellan GPS receiver
must not be used while engaged in any activity requiring the user's full attention to the environment. For instance, the
Magellan GPS receiver should be operated only by vehicle passengers or by the driver when the vehicle has come to a
complete stop. The driver must not attempt to view the display while driving. A climber must not attempt to view the display
while negotiating treacherous terrain. Disregard any unsafe, hazardous or illegal route suggestions.
Magellan maps do not include, analyze, process, consider or reflect any of the following: legal restrictions (such as weight,
height, width, load and speed restrictions); road slope or grade; bridge height, width, weight or other limits; population
density; neighborhood quality or safety; availability or proximity of law enforcement, emergency rescue, medical or other
assistance; construction work zones or hazards; road, sidewalk or waterway closures or conditions; weather conditions;
pavement characteristics or conditions; special events; traffic congestion; time of day.
*Thales Navigation licenses map data from governmental sources such as, but not limited to, US Geological Survey (USGS),
the National Oceanic and Atmospheric Administration (NOAA-NOS) and the Canadian Hydrographic Service (CHS). Thales
Navigation licenses map data from commercial cartography companies such as Navigation Technologies, Navionics, DMTI
and C-Map.
2.4 Care and Use of the Pre-Installed Regional Secure Digital (SD) Card
The Magellan RoadMate 300R comes with an SD card that is pre-installed in the unit. This card contains map data that
covers select regions United States or Canada (see “Regional SD Card Coverage” on page 9) and should never need to be
removed. However, in the event that the SD Card should need to be removed from the unit, for example when switching to a
different regional or full coverage card, reinstalling it is simple and fast. See “Secure Digital (SD) Cards” on page 8 for
instructions on inserting and removing SD Cards.
The SD card slot on your Magellan RoadMate employs what is called a “push-push” method of locking and releasing. In
other words, when you insert the card you must push it to lock it in, and to release it you must push it also.
It is important
to remember to never remove or insert the SD card when the unit is on.
Always make sure to turn the power off when
removing or inserting the SD card. Failure to do so may cause the unit or the data on the SD card to become corrupt or
unusable.
