You will need a compatible device and compatible traffic receiver to use this service. Make sure your device is compatible and that you have the required additional traffic receiver before purchasing this service.
If you have a device that is bundled with traffic, you DO NOT need to purchase standalone traffic service, unless you would like traffic services for a map region that did not come preloaded on your device. Additionally, some regions require a separate, unique traffic receiver.
This traffic service will only work on a compatible device that has City Navigator® NT maps for the traffic coverage area. In other words, if the traffic service is for North America, you must have the corresponding City Navigator NT North America map on your compatible device for traffic to work.
