Garmin GTM 60 GPS Traffic Receiver 010-01031-00 is a small GPS accessory that can shave hours off of your travel time. If you live near or in a big city, traffic is an annoying fact of life. However, this Garmin GPS accessory makes it easy to dodge the traffic and avoid headaches. The GTM 60 attaches to almost any Garmin GPS device, where it receives traffic updates over the unit's HD radio receiver about every 30 seconds, roughly 10 times faster than standard traffic receivers. The GTM 60 then uses Digital 3D Traffic technology to transfer the traffic information to your GPS receiver, which will then notify you and possibly re-route you to a faster way. Garmin packages the Garmin Digital Traffic Receiver with many of their higher end GPS units, but it can also be bought as a standalone GPS accessory. Stay on top of traffic, avoid delays, and zip around the city with authority, all by using the Garmin GTM60 3D Digital Traffic Receiver, one of the handiest GPS accessories around.
