- Navigation
- On-board computer
- A/C display






Component Functions

1. Display and operator control unit
The display and operator control unit is the main part of the PCM system.
It is operated with a so-called dial. A function shown on the display can be selected by turning this dial and activated by pressing it.

2. Navigation unit
The navigation unit is located below the operator control unit. It contains a CD-ROM with special map data which allow the navigation system to orient itself in the road network.

3. GPS antenna
Signals of the Global Positioning System (GPS) are received to determine the position of the vehicle.
The GPS antenna is located in the center of the dashboard and in front of the sun sensor. The GPS antenna is covered by a cover.







The PCM is protected against theft by a device code. Furthermore, the integrated navigation system is also protected by a code against unauthorized users.

Both codes must be input when the system is commissioned at the factory or after replacement of the display and operator control unit and the navigation unit. In both cases, the code for the PCM must be input first.

Only the NAVI code has to be input again after the navigation system has been exchanged.

Only the PCM code has to be input again after an interruption in the continuous power supply (e.g. when the battery is changed) if both codes were input correctly before the interruption.
