GM Service Manual Online
For 1990-2009 cars only

This section presents the basic information you will need to know to operate the navigation system.

The navigation screen shows a number of icons that offer information on a variety of topics.

Use the keys, located on each side of the navigation screen, and the control pad, located at the bottom left corner of the faceplate, to operate the system.

Use the left and right arrows on the control pad to move horizontally on the screen and the up and down arrows on the control pad to move vertically on the screen. Use the ENT (enter) button in the center of the control pad to choose your desired selection.

Once the vehicle is moving, various functions will be disabled to reduce driver distractions.

Hard Keys

The following hard keys are located to the left of the navigation screen:

    •  (Eject)
    • TA
    • SEEK
    • NAV
    • BAND
    • CD
    •  (Audio)
    • SETUP

The function of each of these keys will be explained within this supplement.

The system also has the following reconfigureable soft keys located to the right of the navigation screen. These have hard key labels for easier understanding while in navigation mode. The six keys change functions for different modes of the system.

    • MAP
    • DEST
    • MENU
    •  (Zoom In)
    •  (Zoom Out)
    • BACK

These keys allow you to do the following:

Zoom In


Object Number: 829832  Size: A1

Zoom Out


Object Number: 829831  Size: A1
    • Press Zoom In to get a closer look at the map you are traveling on. Locate a destination easily by zooming in to see a smaller section of the map, if you are close to your destination.
    • Press Zoom Out to see a larger scale of the map, if the destination that you wish to reach is a long distance from your current location. You can also view your highlighted route.

Key Pad

The letters, symbols and punctuation available to you are displayed on the alpha bar. The alpha bar will automatically be available whenever the system needs information from you. Make your selection by pressing the ENT button on the center of the control pad.

To enter a space between the words of a name, you must use the control pad and select the space symbol, which is at the end of the keypad.

To make your name selections easier, the system will only allow you to select a character which can follow the last one entered. For example, if you enter Z, you wouldn't be allowed to follow it with T. The system will highlight the available characters and darken the unavailable characters.

If you select an incorrect character, press the back space symbol button.

If you are unsuccessful when inputting a name, it may need to be selected differently. It is possible that the map DVD (database) may not contain that information. See Database Coverage Explanations .

Numeric Bar

The numbers available to you are displayed. The numerals will automatically be available whenever the system needs you to input a phone number or house address. You can cycle through the list using the control pad and make your selections by pressing the ENT button on the center of the control pad.
