What is "carwings"

CarWings is a vehicle telematics service offered by the Nissan Motor Company to drivers in Japan and United States, now including Canada, Great Britain, and most other countries where the LEAF is sold. It provides mobile connectivity for on-demand traffic information services and internet provided maps displayed inside select Nissan vehicles. The service began in December 1997.

The subscription service replaces the need to periodically update in-car navigation systems that use CD, or DVD installed maps that must be updated with the latest information. The maps are sent by internet connections established through the vehicles TCU (telematics control unit). Unlike other Nissan vehicles that use the driver's cell phone to connect to their data services.
