RGB output to the screen
Information to the GPS unit consists of signals received from GPS satellites via the GPS antenna.
The navigation system requires at least three satellites to be able to calculate the vehicle's position.
Power is supplied to the GPS unit from the multimedia module (MMM). The GPS unit is integrated in the multimedia module (MMM).
Note! If the GPS signal is diagnosed as missing, the signal should be checked outdoors in an open area as the signal could be blocked if the
vehicle is indoors and surrounding buildings could interfere with reception of GPS signals. It can take up to 12 minutes until the GPS signal has
been captured and the position has been determined.
The TMC signal is transmitted from the antenna amplifier and received by the TMC receiver. The TMC signal is managed in the Multimedia module
(MMM) and the information is then presented on the display screen.
The TMC receiver is integrated in the multimedia module (MMM).
TMC is a standardized code system for traffic bulletins, such as information on road construction. TMC is only available on certain markets.
Functions such as system settings and navigation are presented on the display screen in the center of the dashboard. The Multimedia module (MMM)
transmits RGB signals to 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 screen's menu system can be controlled with the navigation keys on the back of the steering wheel or with the remote control for the screen.
The infra-red receiver for the remote control is in the infotainment control module (ICM) (just under the volume knob). The infra-red receiver at the
upper edge of the monitor is not active.
