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. An over-the-air traffic receiver cable is available as an accessory for all product models. Go to your product page at garmin.com to find and purchase a compatible traffic receiver cable accessory. Traffic data is not available in all areas.
Connect the device to vehicle power using the traffic receiver cable (Mounting and powering the Garmin DriveTrack device in your vehicle).
When you are within a traffic coverage area, your device can display traffic information and help you avoid traffic delays.
