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

When you are in an FM TMC service area in the UK, your  
GTM 21 receives traffic signals as soon as you connect  
it to your Garmin GPS device. You need to be in range  
of an FM station transmitting TMC (Traffic Message  
Channel) data to receive traffic information. You do not  
need to subscribe to a traffic service; your GTM 21 works  
automatically.  
NOTE: The FM traffic receiver and GPS  
device must be in data range of an FM station  
transmitting TMC data to receive traffic  
information.  
When you are outside the UK, your GTM 21 receives free  
FM TMC data available in the area. You can also add FM  
traffic subscriptions for other areas. Check the Garmin  
services.  
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.
