CARWINGS services includes traffic information, Yahoo! Gourmet user-generated restaurant ratings, geo-RSS feeds, etc. To date CARWINGS has only been available in Nissan and a select number of vehicles as part of the onboard navigation system.
It seems Nissan is now willing to open up its proprietary system to other players, at least aftermarket devices. Nissan collects probe data from CARWINGS subscribers to deliver up to date traffic information in Japan. The more customers, the better is the traffic information. This agreement with SANYO will extend this probe data gathering beyond Nissan customers.
