Functions such as Mobile office, system settings and navigation are presented on a 6.5" display screen in the center of the dashboard. The display screen is directly connected to the multimedia module (MMM). The control module transmits all the signals required to control the display screen.

If there is an internal fault in the screen or faults in communication with the control module, the quality of the display on the screen will deteriorate or the screen will stop working completely. A simple way to detect a fault in the screen, or communication problems between the screen and the control module, is to check the appearance of the image on screen.

The menu system on the display screen can be controlled either using the navigation buttons on the reverse of the steering wheel or using the screen remote control. The infra-red receiver for the remote control is on the infotainment control module (ICM).
