GM Service Manual Online
For 1990-2009 cars only

This section includes basic information about the map database.

The maps are stored on a DVD-ROM. The 48 contiguous United States, Hawaii, and Canada are contained on one disc. The map database includes interstate freeways, state highways, country roads, and major and general streets.

Refer to the "Navigation System Map Disc" manual to view the explanation of map coverage. The map disc manual will be in the map DVD case when the vehicle is delivered from the factory.

Installing the DVD Map Disc

Your dealer may have installed the map DVD. If the DVD was not installed, do the following:

  1. Turn the ignition on.
  2. Press and hold the eject key, for about 10 seconds, to tilt the screen forward.
  3. Load the map DVD into the DVD slot by inserting it partway. The system will pull it in.
  4. Notice: Pressing directly on the navigation screen may cause damage. Repairs would not be covered by the vehicle's warranty. Do not press directly on the navigation screen.

  5. To close the screen, slightly push up on the two outer top corners until the screen is in position, then push the screen in, by pushing on the four outer corners, until you hear a click.

Once the screen is closed, you will have the following two language choices:

    • ENG (English)
    • FR (French)

Select the language at this time. See "Language" under Configure Menu for more information. Once a language has been selected, touch the NEXT screen button to plan a route. The map will appear showing your current vehicle position.

When the DVD map disc is not loaded, you will not be able to use the navigation portion of the system.

  1. Turn the ignition on.
  2. Press and hold the eject key to tilt the screen forward.
  3. Once the screen is tilted forward, press the eject key next to the DVD map disc slot. The disc will eject.

Map Adjustments and Scales

The system allows you to adjust the scale of view on the map. The map will scroll automatically based on the direction you are traveling.

To view a larger or smaller scale of the map, touch zoom in or zoom out. The scale of a map can range from 1/32 of a mile (0.05 km) to 128 miles (206 km). See "Hard Keys" under Using the Navigation System for more information.
