Save drive time, gas and your sanity by adding traffic services to your compatible Garmin with the help of the GTM 21, a portable traffic receiver. Similar to the GTM 20, the GTM 21 is an integrated FM TMC (Traffic Message Channel) traffic receiver, antenna and cigarette lighter adapter. It receives digital information (where available) on traffic and road construction tie-ups and sends it to your Garmin device to offer an alternate route. The GTM 21 is a fully portable, plug-and-play design that uses a 12-volt cigarette lighter adapter. No professional installation required. Just use the suction cups to attach the antenna to your vehicle's windshield. Then plug the GTM 21 into your compatible Garmin device, and you're ready to receive 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 21, 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.| Product Description | Garmin GTM 21 - TMC module for GPS receiver | | Product Type | TMC module for GPS receiver |
