Why waste your time stuck in traffic?

Save drive time, gas, and your sanity by adding traffic services to your compatible Garmin with help of the portable GTM 12.

New Compact Design and Easy-to-install Antenna

The GTM 12 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. The GTM 12 features a new compact design and includes an antenna suction cup mount — making it easy to install.

Avoid Traffic Tie-ups

TMC data is available in a fast-growing number of cities throughout North America and Europe, and 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 12, 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 12 is a plug-and-play FM RDS-TMC receiver that does not require professional installation.


Subscription Information

Traffic services are available only in select cities where coverage exists. A subscription may be required to enable traffic capability.

Throughout most of Western Europe, basic TMC data is a free public service, accessible through a number of providers. In France and the UK, premium service provided by TrafficMaster requires a subscription. In the U.S., a subscription to the Total Traffic Network is required.

The GTM 12 comes in the configurations listed below. Visit our FM TMC Traffic Service pages to extend your current service or purchase a service plan for an additional area.
