On-board monitor system
Information relating to on-board computer, GPS navigation, television, video recorder, video text, radio, telephone, independent heating/ventilation and sound control can be displayed on the on-board monitor.
The on-board monitor system consists of the following main components:
- On-board monitor control panel (BMBT):
The control panel for the on-board monitor is the keypad with which the on-board monitor system is operated. The key functions are routed via the I-bus to the relevant control units.
- LCD monitor:
The LCD monitor is integrated in the control panel (BMBT). It receives all screen information from the video module (VM).
- Video module (VM):
The video module generates video signals and routes them to the LCD monitor. The video module forwards sound signals such as TV sound and navigation sound to the radio.
- Navigation processor (if GPS navigation installed as optional equipment):
Once the driver has entered a destination, the navigation computer can calculate a driving route from the current location and provide related visual and acoustic information. Various sensors supply information regarding the current position, vehicle direction and route.
- Radio
The radio is operated from the control panel for the on-board monitor via the I-bus. It features inputs for the cassette and TV/navigation sound line. The speakers or DSP amplifier (optional) are connected to the output.
The DSP amplifier supplies high output to the 16 speakers connected to it and provides optimum sound quality.
The individual components are linked as follows:
- The on-board monitor control panel and video module are interlinked via the I-bus.
- The navigation computer is connected to the video module by means of a separate data link (ARCNET), i.e. it is not a direct I-bus user.
- The video signals from the video module are transferred via 3 shielded lines (RGB) to the LCD monitor.
- The background lighting is controlled by a line between the on-board monitor control panel and LCD on-board monitor.
