* OnStar services require vehicle electrical system (including battery), wireless service and GPS satellite signals to be available and operating for features to function properly. OnStar acts as a link to existing emergency service providers. Subscription Service Agreement required. As part of an industry-wide change in the North American wireless telecommunications industry, wireless carriers are transitioning to digital technology and will no longer support the analog network beginning in early 2008. Without the analog network, we can't ensure the coverage that will allow us to provide subscribers, with analog hardware, the services they expect from us. As a result, as of January 1, 2008, OnStar service in the United States and Canada will be available only through vehicles that are capable of operating on the digital cellular network, which may require the purchase of a system upgrade for eligible vehicles.
