DETROIT, Mich. — OnStar, which is now a standard OEM feature on all Cadillac professional vehicles, has introduced two new navigational services to complement and enhance its Turn-by-Turn Navigation system.

These features enable Cadillac to offer vehicles with embedded navigation systems and more options, according to the General Motors' subsidiary.

The first new service is OnStar Destination Download, which enables MY2009 OnStar subscribers with screen-based navigation systems to download directions to their navigation screen by connecting to an OnStar advisor while driving.

The second service, OnStar eNav, allows subscribers with a Turn-by- Turn Navigation-capable vehicle (MY2006 to present) to find and save destinations on MapQuest.com, and have those destinations sent to their vehicle’s OnStar Turn-by-Turn Navigation system.
