This section includes basic information that you need to know about the map database.

Regional and Interstate Maps

The maps are stored on 1 DVD for the United States and Canada.

To load the map DVD, do the following:

  1. Turn the ignition to ON.
  2. Insert the DVD, label side up, partway into the DVD ROM player located above the Navigation System screen.
  3. Load only one DVD at a time.

    It will take approximately 20 seconds to initialize the DVD data.

If you experience a problem with the DVD, check the following:

    • Did you insert the DVD label side up?
    • Are you using only one DVD?

Once the DVD is loaded correctly, you will see the following choices on the Navi System Startup screen:

    • Select a language (the default language is English)
    • Agree

You can change the language from English to Spanish or French, or you can select Agree to go to the navigation screen. See Setup Menu for more information. The map will appear with your current vehicle position on the map.

If your current vehicle position is incorrect on the map, see "Veh (Vehicle) Position" under Setup Menu . See "Plan a Route" in Navigation Menu for more information on planning routes.

Map Database

The map database shows the current map contained in the player and the current vehicle location on the map.

Map Adjustments

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

To view a larger or smaller scale of the map, press the multi-function button next to the Zoom In or Zoom Out prompts at the right of the screen. See "Zoom In/Out" listed previously in this section for more information on these prompts.

Map Scales

The scale of a map can range from 1/64 of a mile (25  km) to 80 miles (128 km).
