This section includes basic information about the map database.

The maps are stored on a DVD-ROM. The 48 contiguous United States and portions of Canada are contained on two discs. To minimize the necessity of changing the discs, both map discs cover US6, US7, and Canada.

DVD Map Disc Messages

If an error appears on the display and/or the map disc comes out, it could be for one of the following reasons:

    • The map disc was installed into the CD slot. See "Installing the DVD Map Disc" previously.
    • It is very hot, when the temperature returns to normal, the map disc should play.
    • The vehicle is being driven on a very rough road. When the road becomes smoother, the map disc should play.
    • The map disc is dirty, scratched, wet, or upside down.

If any error occurs repeatedly or if an error cannot be corrected, contact your dealer/retailer.

Ejecting the DVD Map Disc

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

(Map DVD Eject): Press the eject key, located next to the map DVD loading slot, to eject the map disc. Pull the disc out. The map DVD slot is the slot directly below the display screen.

Handling the DVD Map Disc

When handling the DVD map disc, be careful of the following:

    • Handle the disc very carefully to avoid contamination or flaws. Signals may not read out properly if the disc gets contaminated or flawed.
    • If the disc gets 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.
    • Do not use the disc to rest on while writing or drawing using any writing utensil or attach a seal to any of the sides or the disc.
    • Do not keep the disc in direct sunlight, high temperatures, or humidity.
    • After using the disc, place it back into the original case.

Map Adjustments

The scale of view on the map can be adjusted. As you drive, the map scrolls automatically based on the direction you are traveling.

Map Scales


Object Number: 1414039  Size: A1

To view a larger or smaller scale of the map, touch the map scale arrows.

Change the level of map detail by either zooming in or zooming out using the arrow screen buttons or by touching the scale on the bar. The system adjusts the map accordingly. The scale of a map can range from 1/32 of a mile (50 m) to 128 miles (256 km).

Scrolling the Map


Object Number: 811648  Size: A1

Touch anywhere on the map screen twice and the scroll symbol appears. Use this feature to scroll across the map.

Hold your finger in any direction outside of the scroll symbol and the map continues to scroll in that direction until your finger is removed from the map screen.

If scrolling while the vehicle is in P (Park), the system scrolls initially at a slower rate. It increases if you continue touching the map screen.

If scrolling while the vehicle is in motion, there is one scroll speed and a limited distance to scroll. Keep touching the map screen to scroll for a longer distance.

If the scroll feature is used to scroll the map and the vehicle icon becomes lost, press the map hard key to return to the current vehicle location on the map.

When scrolling on the map, the system displays the address of the scroll symbol location and the distance from the vehicle's current position to the scroll symbol location.

Use the scroll feature on the map to set a destination. See "Map" under Destination for more information.
