This section includes basic information about the map database.

Map Coverage

The maps are stored on a DVD-ROM. The 48 contiguous United States, Hawaii, and Canada are contained on one disc.

Refer to the "Navigation System Map Disc" manual to view a detailed explanation of map coverage and detailed city lists in each region. This manual is in the map DVD case when the vehicle is delivered from the factory.

Installing the DVD Map Disc

Your dealer/retailer may have installed the map DVD. To load the DVD if it was not installed:

  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 pulls 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.

  4. 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 a click is heard.

Once the screen is closed, there are two language choices:

    • ENG (English)
    • FR (French)

Select the language. 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 appears showing the current vehicle position.

Ejecting the DVD Map Disc

When the DVD map disc is not loaded, the navigation portion of the system cannot be used.

  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 ejects.

    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.

  4. 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 a click is heard.

Handling the DVD Map Disc

When handling the DVD map disc:

    • Avoid disc contamination or flaws. Signals may not read out properly if the disc gets contaminated or flawed.
    • Avoid getting the disc soiled. Use a soft cloth to gently wipe it out from the center of the disc to the outside. Do not use photographic record cleaner, solvents, or other cleaners.
    • Avoid using the disc to rest on while writing or drawing with any writing utensil, or attaching a seal to any of the sides of the disc.
    • Avoid keeping the disc in direct sunlight, high temperatures, or humidity.
    • Remember to place the used disc back into the original case.

Map Adjustments and Scales

The map scrolls automatically based on the direction of travel. The scale of view on the map can be adjusted.

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 (50 m) to 128 miles (200 km). See "Hard Keys" under Using the Navigation System for more information.
