Garmin GTM 11 Traffic Receiver

Product Code: GART11

Garmin 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 across Great Britain (England, Scotland and Wales), 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.

The GTM 11 is a plug-and-play FM RDS-TMC receiver that does not require professional installation.

Compatibility: Compatible with the Garmin nuvi 300, nuvi 310, nuvi 350, nuvi 360, nuvi 370, StreetPilot c340, StreetPilot 2720, StreetPilot 2820.

Garmin GTM 11 Traffic Receiver has been discontinued.

Garmin GTM 11 FM TMC Traffic Receiver

The Garmin 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 across Great Britain (England, Scotland and Wales), 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.

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.

The GTM 11 is a plug-and-play FM RDS-TMC receiver that does not require professional installation.
