North Up: This feature orients the map with North at the top of the map screen, regardless of which direction you are driving.

Heading Up: This feature orients the map with the direction you are driving at the top of the map screen, regardless of which direction is North.

Turn List: This feature lists information on your next three maneuvers, including the distance to the turn, and street names.

Map: This feature will display your current position, with the calculated route highlighted.

Single: This feature allows one map to be displayed.

Split screen: This feature allows two maps to be displayed, which can be independently adjusted in both scale and map orientation. When in Split screen mode, the right screen can be chosen to display Arrow or Turn list guidance modes.

For more information on the symbols that can appear on a map screen, see Symbols .

Volume

This system has voice guidance prompts that provide various messages as you approach points where you need to maneuver your vehicle, such as an intersection.

To adjust the volume of the voice prompts you receive from the system, do the following:

  1. Select Volume from the main navigation menu.
  2. Use the joystick to adjust the volume from 1 to 7.
  3. Once you have reached the desired volume level, you can press the BACK key to return to the previous screen.

With Adaptive volume control, the volume of voice prompts will increase automatically once the vehicle exceeds 50 mph (80 km/hr). Select On to activate this feature.

If you do not need voice guidance, you may also choose to turn the prompts off.
