Traffic can't always be prevented. But with Garmin's GTM 20 portable traffic receiver, you can often avoid them.
Avoid Traffic Tie ups
The GTM 20 is an integrated FM traffic Receiver which provides real time traffic alerts on traffic and road construction tie-ups and sends it to your compatible Garmin navigation device to offer an alternate route. The receiver also acts as an in-vehicle power charger. The GTM 20 traffic receiver is compatible with the nüvi 760, 765 and the zūmo range.
Power your nüvi and get lifetime¹ traffic updates all with one cable.
