 12 FM TMC Traffic 

Receiver receives Traffic Message Channel (TMC) 

information broadcast over the FM radio data system. 

When a traffic message is received, your Garmin 

GPS device 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 GPS 

device 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 Garmin GPS device.

Your GTM 12 has a 15-month subscription to Clear 

Channel’s Total Traffic Network service. 
When you are in an FM TMC service area in the 

United States, your GTM 12 receives traffic signals 

as soon as you connect it to your Garmin GPS 

device.  
Your GTM 12 receives free FM TMC services 

available in Europe. 
You can renew your subscription and add FM traffic 

subscriptions for other countries. Check the Garmin 

available services.
