GM Service Manual Online
For 1990-2009 cars only

Before you begin to operate the navigation system, read this manual thoroughly to become familiar with it and to understand how the system works.

The navigation system allows you to do the following:

    • Plan a route with provided turn-by-turn route and map guidance with voice prompts.
    • Select a destination using various methods and choices.
    • Receive broadcast announcements on traffic and emergency alert communications.

The information in the system may not always be complete. Road conditions such as prohibited turns, detours, and construction zones, change frequently. It is important to consider whether you can follow the directions given by the system for the current conditions.

When getting started, you may set the navigation system to your preference using various options. To do so, reference the following topics:

    • To adjust screen appearance, language, clock, or other options, see "Playing the Radio" under Navigation Audio System .
    • To adjust English/metric measurements, voice guidance volume, or other navigation settings, see Setup Menu .
