Garmin GTM 12 TMC module for GPS receiver

Save drive time, gas, and your sanity by adding traffic services to your compatible Garmin. The GTM 12 is a FM RDS-TMC traffic receiver. It receives digital information (where available) on traffic, road construction and weather-related tie-ups, which your compatible Garmin uses to offer an alternate route. In the U.S., the GTM 12 traffic receiver comes with a 15-month trial subscription to Clear Channel TMC. Traffic services are available only in select cities where RDS-TMC coverage exists.
