Contrast/Brightness

To adjust the contrast or brightness of the navigation screen, choose the desired option by selecting it with the joystick. Use the joystick to raise or lower the contrast or brightness to the desired level. You will see the screen change as you adjust the contrast or brightness.

Screen Color

When the headlamp switch is turned off, the navigation screen will change to a lighter background and change colors for better viewing in the daytime. At night, the screen will go to a darker background. You can select Auto for automatic adjustment.

You can also select day or night mode regardless of the lighting conditions. The Day setting leaves the system in the day mode. The Night setting leaves the system in the night mode.

Beep

With this feature on, a beep will sound every time a key is pressed on the navigation system. Choose Off if you do not want to hear a beep whenever a key is pressed.

Language

Your vehicle has been set for the English language, but you may also select French for all instructional text and voice prompts. However, names on the map when using the navigation functions will not change.

If you wish to change the language, the map DVD must be inserted. Then, do the following:

  1. Press the Language key under the Setup menu. A caution will display.
  2. Using the joystick, scroll to the desired language and press the joystick to select it.
  3. Select NEXT to change the display back to the map screen.

If the language is changed from English, the menu screens will not match word-for-word as they appear in this manual.

If you accidentally select a language you do not understand, eject the map DVD and insert it again. You will then be able to select a different language when the system restarts.
