GM Service Manual Online
For 1990-2009 cars only

Read this manual thoroughly to become familiar with how the navigation system operates.

The navigation system includes navigation and audio functions.

Keeping your eyes on the road and your mind on the drive is important for safe driving. The navigation system has built-in features intended to help you do this. Some features may be disabled while driving. Note, these functions are grayed-out. A grayed-out function indicates it is not available when the vehicle is moving.

All functions are available when the vehicle is parked. Do the following before driving:

    • Become familiar with the navigation system operation, hard keys on the faceplate, and touch-sensitive screen buttons of the navigation system.
    • Set up the audio by presetting favorite stations, setting the tone, and adjusting the speakers.
    • Set up the navigation features before beginning driving, such as entering an address or a preset destination.
    • Set up the phone numbers in advance so they can be called easily with the press of a single button or a single voice command (for navigation systems equipped with phone capability).

Caution: Taking your eyes off the road too long or too often while using the navigation system could cause a crash resulting in injury or death to you or others. Focus your attention on driving.

Caution: Avoid looking too long or too often at the moving map on the navigation screen. This could cause a crash and you or others can be injured or killed. Use the turn-by-turn voice guidance directions whenever possible.

Use the navigation system to:

    • Plan a route.
    • Select a destination using various methods and choices.
    • Follow turn-by-turn route and map guidance with voice prompts, only if permitted by traffic laws, controls, and conditions.

Always be alert, obey traffic and roadway laws, and instructions, regardless of the guidance from the navigation system. Because the navigation system uses street map information that does not include all traffic restrictions or the latest road changes, it may suggest using a road that is now closed for construction or a turn that is prohibited by signs at the intersection. Because the system uses limited information, you must always evaluate whether following the system's directions is safe and legal for the current conditions.

When the navigation system is turned on, a screen may appear with the information below, and you must read and acknowledge the information it contains.

After you acknowledge the start up information you will be able to access the NAV (navigation) and DEST (destination) functions. Once accessed, you can enter or delete information in the navigation system or access other functions. See instructions later in this section.

Deleting Personal Information

This navigation system can record and store destinations. At times, such as when you are disposing of the vehicle, you may want to delete these destinations. Refer to the following sections to delete the destination information that has been stored.
