OnStar Description and Operation: Notes

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

This vehicle will be equipped with either the 2.0 or 2.6 version of the OnStar® system. Both systems consist of a vehicle interface unit (VIU), vehicle communication unit (VCU), GPS antenna, cellular antenna, microphone and OnStar® button assembly. Both the systems interface with the vehicle audio system.

The OnStar® system version 2.0 provides the customer with impact detection, navigation instructions, emergency services, stolen vehicle tracking and recovery service, roadside assistance, door unlock, light flash and horn pulse.

The OnStar® system version 2.6 provides all the same features as version 2.0 with the addition of a hands free cellular phone. The OnStar® Personal Calling feature, if equipped, uses voice commands for dialing and programming.
