The controller can be used to activate the Service mode. In the Service mode, additional information on, e.g., radio, navigation or GPS information can be displayed.
You can exit the Service mode by pressing the menu key.
After successfully calling up the Service mode, you reach a menu structure that enables choice of the service functions. There are currently service functions available for the TV, radio, navigation and GPS. To check the components, make the corresponding menu in the menus that follow.
To check input data in the navigation, enable the item NavInfo ON in the Service mode in the Navigation submenu. This means that when the Service mode is left, the NavInfo menu item is added at Navigation in the Boardinfo submenu. This menu item can be used to check sensor data from the gyro, the number of active satellites data and wheel speeds while the vehicle is being driven. On leaving the NavInfo menu, this service function is to be disabled once again by calling up the service mode!
