NOTE: The E39 six cylinder models with the On-board Monitor option are equipped with the high version IKE and On Board Computer functions. The On-board Monitor is essentially a control and display unit. All data processing and calculations are carried out by the individual system control modules. The display data is sent to the On-board Monitor over the various interfaces. The On-board Monitor is mounted in the center dash console. It replaces the Radio/Tape Player, MID and DSP control panel (E38) if equipped. It consists of control knobs and buttons for programming and operating the various systems. There is a 5 1/4 inch, color LCD screen for display of all system functions. The tape player drive is also part of the On-Board Monitor unit. However, the radio receiver/amplifier module is now mounted in the trunk. The audio system is controlled from the on-board monitor. Additionally, the systems controlled and programmed through the On-board Monitor include: On Board Computer Navigation system Telephone Code Function Set (on-board monitor setup) Television (Early production only) Digital Sound Processor (DSP) Auxiliary Ventilation Emergency (provides vehicle location and automatically dials telephone for help). Monitor Off (Switches the monitor off). 3 On-Board Monitor and Navigation Systems COMPONENTS ON-BOARD MONITOR ASSEMBLY The on-board monitor assembly is mounted in the center console. following components: It consists of the On-board monitor housing with Cassette tape player. 5 1/4 inch color LCD display screen. BMBT. BMBT is a German acronym meaning, Board Monitor Bedien Tiel. Translated to English this means On-Board Monitor Control Module/Panel. The BMBT is connected to the I-BUS. It provides the same function as the pushbutton inputs and output illumination of the LEDs of the familiar MID.
