Multi-Function Display
The Multi-Function Display (MFD) is the user interface for the navigation system. The MFD is also the interface for the radio, cassette, CD changer, trip computer and telephone functions of the audio system along with the auxiliary heating timer control, DSP functions, television and teletext. The unit comprises a wide screen format LCD monitor and associated control buttons. The unit houses a cassette mechanism hidden behind the screen which tilts down to load / eject the cassette.
The MFD communicates on the I bus with the navigation computer, the CD autochanger (where fitted), the radio unit, the telephone (where fitted), the instrument pack and the video module. The communication with the instrument pack is used for diagnostic communication via the diagnostic DS2 bus.
