Avoid Traffic Tie-ups
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 and sends it to your compatible Garmin device to offer an alternate route. 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.
Plug and Drive
The GTM 12 features a fully portable, plug-and-play design that requires no professional installation. Just use the suction cups to attach the antenna to your vehicle's windshield. Then plug the GTM 12 into your compatible Garmin device, and you're ready to receive data.
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. 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.
GTM 12: Because you have better things to do with your time.

Comments about Garmin Garmin Plug and Play Traffic Receiver:
Used with the Garmin Street Pilot 2720, it is plug and play, but not a worthy investment. Signals are not consistently good enough and accurate enough to justify the money in the Houston Area.
