GARMIN GTM 11 FM Traffic Receiver

Avoid Traffic Tie-ups
The GTM 11 is an FM TMC (Traffic Message Channel) traffic receiver and antenna. It receives digital information (where available) on traffic and road construction tie-ups that your compatible Garmin unit uses to offer an alternate route. TMC data, available in a fast-growing number of cities throughout North America and Europe, gives prompt, accurate notification of accidents, road construction, police, or emergency action, etc. — so you can visually monitor traffic flow and, if necessary, avoid traffic tie-ups.

Receive Real-time Traffic Data
In most areas, depending on the service provider, TMC traffic broadcasts are continuous — there's no waiting for scheduled traffic news updates or random alerts. With the GTM 11, you see traffic developments in real-time, as they happen, so you can make the right decision sooner. The system alerts you when a traffic problem is on your route and proposes an alternate route to avoid the incident. Because traffic broadcasts are received via a "silent" FM data channel, you can still listen to music or news programming on your car radio without interference from incoming FM traffic data transmissions.
