NFORMATION

Your c550 can use an FM TMC Traffic Receiver to receive traffic 
information broadcast over the FM Radio Data System. When 
a traffic message is received, your unit displays the event on the 
map and can change your route to avoid the traffic incident.  For 
participating subscription providers and coverage areas, refer to 
the Garmin Web site at 

The GTM 20 provides power to the c550 as well as traffic 
information.

1.  Plug the power connector into the back of the c550. 
2.  Plug the other end into a 12-Volt receptacle in your 

vehicle. 



 

NOTE: You can only 
access the traffic 
information and settings if 
the c550 is connected to an 
FM Traffic Receiver. 



 

NOTE: The FM Traffic 
Receiver and c550 must 
be in data range of an 
FM station transmitting 
TMC 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.
