ECO mode BMW 3 SERIES 2004 E46 Wide Screen On Board Monitor Workshop Manual

7
Widescreen board monitor
Principle of operation
The on-board monitor is an input and display device that performs no internal calculations.
Inputs from the control panel buttons and knobs are converted into I-bus (K-bus E46)
signals by the BM control panel. All of the devices controlled by the BM are connected to
the I/K bus interface.
The navigation computer contains the graphics stage integrated into the navigation
computer housing. Request for on-board monitor displays are made to the navigation
computer via the I/K bus. The navigation computer generates the RGB video signals and
transmits them via 3 shielded wires.
Audio signals generated by the cassette drive are sent via traditional audio wires (4) to the
radio (located in the trunk or cargo area) for output to the audio system amplifier.
