On-Board Monitor and Navigation Systems

ON-BOARD MONITOR SYSTEM
The On-board Mon tor System was introduced as opt onal 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 Nav gat on system s ncorporated 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
adio/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. emove 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. emove the on-board monitor wood trim
4. With the on-board monitor wood trim removed,
unscrew the four large torxTM screws as shown.
5. Pull the on-board monitor assembly out of the center
console.
For complete procedures refer to group 65 repa r manual n TIS.

tr m cover
Mark I
NAVIGATION
COMPUTER
MODULE
It contains a micro-
processor and CD
drive for navigation
system operation.
The navigation
computer is linked
directly to the
video module
which provides the
visual and audio
output instructions
for the navigation
system.
AUDIO SYSTEM
AMPLIFIER
RADIO
RECEIVER
AUDIO SYSTEM
CD CHANGER
GLOBAL POSITIONING RECEIVER MODULE (GPS)
The module determines the exact position of the vehicle from known orbits of GPS
satellites. The GPS receiver interfaces with the Navigation computer module for
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 ed,
Green and Blue
video signals for the
on-board monitor
LCD screen. The
GB 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 GB signals to
change the on-
board monitors
display and sends
the audio signals to
the audio system
amplifier.

On-Board Monitor and Navigation Systems

The follow ng components are located on the rear parcel shelf under the tr m
panel.
MAGNETIC FIELD SENSOR
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.
Carry over components that are part of the On-Board Mon tor / Nav gat on system
nclude:
 Instrument Cluster Control Module (IKE) for On Board Computer calculations
 Multi-Function Steering Wheel (MFL) for radio and telephone control functions.
 Telephone handset for operation of the phone.
 ASC control module for the two front wheel speed sensor inputs.

ON-BOARD MONITOR AND NAVIGATION SYSTEM INTERFACES
I BUS - The On-board Monitor Control Module/Panel is connected to the I-Bus for
communication with the other I-Bus components. Data communication takes place over
the I-Bus between the BMBT and the following modules:
 IKE
 Telephone Handset
 Multi-Function Steering Wheel (MFL)
ARCNET - The Attached Resource
Computing Network is a high speed (2
MB/sec) digital data link. The Navigation
Computer and Video Module are
connected by the A CNET for isolated
high speed navigation system
communication.
The A CNET is made up of two data
wires and a shield similar to the familiar
CAN data link. The shielded A CNET
cable has its own triaxial type connector
ends that are pushed onto their mating
connectors on the modules.
V deo Module Red, Green Blue (RGB) output - The On Board Monitor is connected to
the Video module through the GB connection for the LCD screen displays. Each of the
three color signals is shielded.
