What Type of Traffic Does My Garmin Overlander Use?

In order to receive any traffic information, your Garmin Overlander® GPS navigator needs to be connected to a traffic receiver cable, which is a 12V vehicle power cable with a traffic receiver embedded along the wire. This receiver allows the device to receive FM radio signals with information about upcoming traffic, which it then displays on the map.

Since the traffic receiver is built into the vehicle power cable, your device will not receive traffic information unless the cable is connected to your device and vehicle. Using the GPS device without the vehicle cable, or with a third-party vehicle cable, will result in no traffic information.

NOTE: External Traffic receivers are no longer available for purchase through Garmin. See GTM 60 and GTM 36 Cables are Discontinued for more information.
