ON-BOARD MONITOR SYSTEM
The On-board Monitor System was introduced as optional equipment on the 1997 MY E38s and E39s. It was made standard on the E38 750iL for 1999 and standard for all E38s in 2000. It uses the latest advances in electronic technology to bring new levels of comfort and convenience to the driver and passengers for control of the audio/communication systems. In addition the Mark I Navigation system is incorporated into the total scope of On-board Monitor Control.
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)

On-Board Monitor and Navigation Systems
Introduction
While the instrument cluster provides all of the important vehicle status information to the driver, the on-board monitor is designed as an additional display that can be viewed by both the driver and vehicle passengers. Information relating to the vehicle, navigation, audio system and telephone can be displayed and controlled from a central location.
The wide screen on-board monitor replaces both the 5.5’’ versions in the E38 and E39, and the 5’’ board monitor from the E53 and E46. The wide screen display has a screen size of 6.5’’ and an aspect ratio (length:height) of 16:9.
The benefits of the wide screen design are:
•Larger display area and higher resolution (400X234 pixels).
•Improved display screen technology (Ad-TFT LC).
•Bigger text size.
•Soft keys replace country specific audio function keys.
•Used for all board monitor applications in all markets reducing variants.
•Larger display area makes split screen and magnification features possible (future software enhancements).
16
On-Board Monitor and Navigation Systems
Component Overview
The wide screen on-board monitor consists of:
1.Monitor housing with cassette drive
2.Display screen
3.On-board monitor control panel
Cassette Drive
The cassette drive is located behind the on-board monitor screen. In order to access the cassette, press the “eject” button, the display screen tilts forward to uncover the cassette slot. The images will remain displayed on the screen.
After pressing the “eject” button again or automatically after 15 seconds the display returns to its normal position (cassette must be completely inside or removed). The tilt mechanism for the display screen utilizes anti-trap, if the board monitor detects a sudden change in speed, the display will reverse direction.
17
On-Board Monitor and Navigation Systems
Display Screen and Control Panel
The display screen has a diagonal width of 6.5’’ and an aspect ratio of 16:9 compared to the previous monitors that had a ratio of 4:3. The new screen also uses a Ad-TFT display (Advanced Thin Film Transistor). This type of screen uses ambient light in addition to backlighting in order to illuminate the display. The advantage is a constant contrast and brightness level at all ambient lighting conditions.

On-Board Monitor and Navigation Systems
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.

GPS - NAVIGATION SYSTEM
GLOBAL POSITIONING SYSTEM (GPS)
The BMW Navigation system operates in conjunction with the Global Positioning System (GPS). Utilization of the GPS improves the accuracy and provides redundancy for the Navigation system which also incorporates a dead reckoning system. The GPS was designed by the US Government in the 1970s for military purposes. In recent years it has been made available for civilian use.
There are 24 satellites equally divided among six orbits that are positioned 11,000 miles out in space. Each satellite continuously emits a radio signal. The signals contain short information messages including:
•The exact time the message was broadcast.
•Current latitude and longitude positions relative to the orbit.
