USING FM TRAFFIC
USING FM TRAFFIC
Use an FM TMC traffic receiver to
receive traffic information broadcast
over the FM Radio Data System. When
a traffic message is received, your c550
displays the incident on the map and can
change your route to avoid the traffic
incident. For coverage areas, refer to
the Garmin Web site at
www.garmin
.com/fmtraffic.
NOTE: The FM traffic receiver and
c550 must be in data range of an FM
station transmitting TMC (Traffic
Message Channel) data to receive
traffic information.
NOTE: Garmin is not responsible
for the accuracy of the traffic
information. The FM traffic receiver
simply receives signals from the
traffic service provider and shows
that information on your c550.
NOTE: You can only access the
traffic information if the c550 is
connected to an FM traffic receiver.
