AutoDJ (information content)
Some of the services available include traffic and weather information, horoscopes, including sports scores and game status. The information is then displayed on the screen. The downloaded text, and navigation can be read audibly by the navigation system. Starting September 20, 2006, CARWINGS was made available to subscribers on their home computers, by registering the URL of a site that offers RSS, which is then relayed to a separate "information channel" that is also displayed.
