PRINCIPLE OF OPERATION
Traffic message channel (TMC) stations
are broadcast on the FM waveband. TMC
is a feature that receives traffic alerts
which can be used to plan alternative
routes and avoid hold ups.
USING TMC
Press the TA or TRAFFIC button to show
the traffic menu page.
Traffic announcement
Traffic announcement (TA) can be turned
on or off via this menu. If switched on a TA
indicator is shown in the information
border of the status bar.
Stations which broadcast on the FM
waveband and carry traffic programme
(TP) information are identified by TP
shown in the screen display. With TA
switched on the unit will respond to these
announcements and interrupt music
playback. After the announcement has
ended music playback will resume.
Ending traffic announcements
The unit will return to normal operation at
the end of each traffic announcement. To
end the announcement prematurely, press
the TA, TRAFFIC, RADIO or CD button
during the announcement.
Using TMC messages
Select the required item to display a list of
TMC messages. See General
Information (page 78). This is only an
overview display which gives very basic
information. Select the message you
require further information on and another
screen will be displayed giving full message
details on incident location etc.
You may either select a view which shows
messages only affecting your programmed
route, or a view which shows all messages
received. Press function button 1 to change
the view.
Hazard spot warning (depending
on country)
Note: The availability of this feature will
vary from country to country.
The system supports a hazard spot
warning feature which informs you with
visible and audible feedback about
hazardous traffic areas. The system is off
by default. You can switch the system on
and off using the information display. See
Information Displays (page 78).
