The GPS built into OnStar pinpoints the driver’s location and lays out a path to the chosen destination. The system is similar to that offered in typical navigation systems, and is supplemental to OnStar’s person-to-person contact with the driver. OnStar’s crash notification, door unlocking and e-mail services continue as part of the system’s basic package.–Jim DunneChicago Auto Show 8: Toyota Tundra, Honda Civic Si Sedan Concept Chicago Auto Show 7: Nissan Quest, Hyundai EntourageChicago Auto Show 6: Dodge Rampage ConceptChicago Auto Show 5: Lexus ES 350Chicago Auto Show 4: Dodge Caliber SRT4, Lincoln NavigatorMERCEDES-BENZ ML63 AMGMERCEDES-BENZ R63 AMGMercedes also North American-debuted its S600 flagship in Chicago.Nice and tidy, the S600’s 6.0-liter twin-turbo V12 makes 517 hp and ungodly amounts of torque.
