Receiving traffic data using a traffic receiver
Heated (metallised) windscreens could degrade the performance of the traffic receiver.
A traffic receiver receives traffic data from an over-the-air broadcast signal, where available. To receive over-the-air traffic data, the device must be connected to vehicle power using a traffic-compatible power cable. A traffic receiver is included with some product models (Traffic). .
Traffic data is not available in all areas. For information about traffic coverage areas, go to garmin.com/traffic.
Connect the device to vehicle power using the traffic-compatible power cable (Mounting and powering the dēzl device in your vehicle).
If your product model includes traffic data, the vehicle power cable included with your device is traffic-compatible.
When you are within a traffic coverage area, your device can display traffic information and help you avoid traffic delays.
