This section includes basic information that you need to know 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.

    • If 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.
    • You are driving 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.

Map Adjustments

The system lets you adjust the scale of view on the map. Also, as you drive, the map scrolls automatically based on the direction you are traveling.

Map Scales


Object Number: 1470126  Size: A1

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

You can 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 (0.05 km) 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.

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

If scrolling while your vehicle is in motion, the system will scroll to that location and stop.

If you have used the scroll feature to scroll the map and your vehicle icon becomes lost, press the NAV (navigation) hard key to return to the current vehicle location on the map.

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