Save drive time, gas, and your sanity by adding traffic services to your compatible Garmin with the help of the portable GTM 12, a plug-and-play traffic receiver.Avoid Traffic Tie-upsThe 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 DriveThe 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 DataIn 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.
