On-Board Monitor and Navigation Systems

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)
 Auxiliary Ventilation
 Emergency (provides vehicle location and

automatically dials telephone for help).

 Monitor Off (Switches the monitor off).

COMPONENTS

ON-BOARD MONITOR ASSEMBLY

The on-board monitor assembly is mounted in the center console. It consists of the
following components:

 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.

REMOVAL OF ON-BOARD MONITOR ASSEMBLY FROM CENTER CONSOLE

The on-board monitor is removed from the center console
as an assembly as follows.

1. Remove the wood trim from the dash on both sides of
the on-board monitor.

2. Unscrew the metal plates (E38) or unhook the latches (E39)
from each side of the on-board monitor and loosen the
recessed screw from the lower edge of the wood trim.

3. Remove the on-board monitor wood trim

4. With the on-board monitor wood trim removed,
unscrew the four large torx

TM

screws as shown.

5. Pull the on-board monitor assembly out of the center
console.

For complete procedures refer to group 65 repair manual in TIS.

determining the vehicle position.

NAVIGATION COMPUTER REMOVAL:

To remove the nav. computer from the mounting
bracket insert four small phillips head
screwdrivers into the four holes on the face
plate. Push the screwdrivers in past a slight
detent. Pull the nav. computer out of the mounting bracket.

VIDEO MODULE

The video module
generates the Red,
Green and Blue
video signals for the
on-board monitor
LCD screen. The
RGB signals are for
all functions of the
on-board monitor
including the nav.
system.

The video module
also serves as a
data memory for the
navigation system.
As needed the
video module
instantly provides
the RGB signals to
change the on­board monitors
display and sends
the audio signals to
the audio system
amplifier.

The magnetic field sensor is a
small micro processor. It is used
while the navigation system is
operating to determine the
vehicles direction of travel.

GLOBAL POSITIONING
RECEIVER ANTENNA

The antenna picks up the signals
from the satellites and transmits
them to the GPS module.

connected by the ARCNET for isolated
high speed navigation system
communication.

The ARCNET is made up of two data
wires and a shield similar to the familiar
CAN data link. The shielded ARCNET
cable has its own triaxial type connector
ends that are pushed onto their mating
connectors on the modules.

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).

17

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.

18

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.

Workshop Hints

Service mode

Access for the radio, on-board monitor and navigation service modes is available through

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.
