If you have a Garmin device with a traffic receiver but you are not receiving any traffic information, there are a number of troubleshooting steps you can take to resolve the issue.
It is also possible that the traffic service has been disabled. To confirm whether the service is enabled:
If the traffic is disabled, you may enable it here.
If your traffic subscription has never been activated, you will also need to acquire GPS satellite signal to activate the subscription. After checking your coverage area using the links listed above, plug the traffic receiver/vehicle power cable into the vehicle and then into the GPS device or cradle. Allow the device to receive GPS signal along with the FM signal. This process may take up to 20 minutes.
If you have previously received traffic signal with your receiver, you may still receive traffic signal even without satellite signal. In this case, the device will use your last known position to determine coverage.
If you're still not receiving traffic after following all the steps and tips above, please contact Product Support.
