The OnStar® service offers customers unique communication, navigation, security, and customer assistance features. These are made possible by the national cellular telephone infrastructure, the military GPS navigation system, the OnStar® Center (OC) and the vehicle installed OnStar® equipment. The vehicle installed equipment will be referred to as the Vehicle Communication Platform (VCP). The VCP includes a cellular telephone, cellular data modem, and GPS receiver.

This equipment requires a data and/or voice interface with the OnStar® Center to provide any services. A monthly service fee is charged for OnStar® services, similar to the billing arrangement used by cellular telephone carriers or cable TV operators. This fee includes all cellular air time charges.

OnStar® Services

OnStar® offers these following services:

Impact Detection

Following a front air bag deployment, the VCP automatically notifies the OnStar® Center that an accident has occurred. The OnStar® Center will respond by attempting to establish voice contact with the occupant(s) of the accident vehicle on the cellular equipment. If the driver does not respond or requests help, the OnStar® Center advisor contacts the nearest emergency services provider with an accident report and vehicle location.In the event that the cellular connection to the vehicle is terminated, the OnStar® Center advisor will attempt to reestablish contact with the vehicle. If this step fails to reconnect the OnStar® Center advisor with the occupants of the vehicle, emergency services will be dispatched to the vehicle's location.
