If your device comes with SUNA Traffic Channel as standard “in the box”: No additional hardware is required and the SUNA subscription runs for the lifetime of the device. The device should be receiving live traffic updates automatically. Please refer to your device manual for further information for your specific device and settings. Please check to ensure that you are in a broadcast area by checking our coverage map.
If you are confident you are within a broadcast area and still require further assistance, please refer to the retailer of purchase.
If you have upgraded your device by purchasing a TMC accessory or antenna, you will need to ensure that you have the correct version of maps installed. Please check against your specific device for further information.
