1 General Description
The Occupant Information Navigation System (navigation system) fitted to Sedan and C oupe vehicles is adapted from
the Siemens VDO Dayton MS 5400 Navigation S ystem. T he MS 5400 has been modified to Holden specifications for
easy vehicle installation.
The navigation system uses three principal technologi es:
• The navigation processor us es the vehicle speed signal (VSS) and an internal gyroscope
• Global Positioning System (GPS)
• Digital road mapping
The navigation system consists of the following components (refer to Figure 12L – 1):
• Processor assembly (1)
• Display assembly (2) and escutcheon (3)
• GPS antenna assembly (4)
• Remote control assembly (5) with presenter (6)
• Speaker assembly (7)
• Wiring harness and cockpit wiring h arness (8 )
The following modifications are made to the floor console cover assembly to accommod ate the navigation system:
• Holes are drilled in the floor console cover assembly so the navigation remote control assembly and presenter can
be fitted
• The floor console cover assembly is cut to specific ation to allow for the installation of the navigation display
assembly
NOTE
Although there are obvious interior trim and body
shape differences between the Sedan and
Coupe, the navigation system remains the same
for all except for the h arness lengths and harness
clips.

Vehicle Speed and Direction
The vehicle speed sensor and the gyroscope work together to provide direction and speed. In conjunction with the
position signal received from the GPS, the vehicle speed sensor and gyroscope provide the processor with the
necessary data to produce vehicle navigation information to the user.
Global Positioning System
The GPS is a series of 27 satellites (nominally 24) which orbit the ground at an altitude o f 20 372 km. The signals from
four satellites must be received by a GPS receiver to get an accurate three-dimensional position. If only three satellite
signals are received a position is attained, but with reduced accuracy. The position calculated by the GPS receiver is
accurate to between 30 and 100 metres. GPS reception may be interrupted, especially due to the nature of the
navigation system, in the following instances:
• between tall buildings;
• in car parks, tunnels or under bridges;
• in forests or avenues;
• during storms;
• in valleys and mountains; and
• if the GPS antenna assembly and the positi on of the satellites are not favourable du e to the satellite’s orbit
Digital Road Map
The digital road map is supplied by Siem ens VDO Dayton. The map is contained on a Compact Disc (CD–ROM), which
is read by the processor assembly. This CD must be inserted into the processor assembly for the system to work.
Update versions of the map are available from Holden Spare Parts Organisation (HSPO).
Navigation System Page 12L–8
Page 12L–8
1.1 General Operation
NOTE
For information on the navigation system
operation, refer to the Satellite Navigation
Handbook Supplement supplied with the
navigation system.
The navigation system operates in the following manner:
• Initially, with power supplied, the navigation display activates and the receiver acquires a GPS signal. This provides
a position accurate to within 30 to 100 metres. T his position is transposed onto the digital road map and shown on
the navigation display in the form of an arrow. Initially, the vehicle may not be shown in its exact position, as the
navigation system may not be calibrated.
• The user can no w enter a dest ination using the navigation system menus. The remote control, which can be used
while in its cradle or pointed at the display, is used to navigate through the navig ation system menus. The map
screen highlights the route to be taken.
• The navigation s ystem begins calibration automatically when the vehicle moves. The VSS provides electrical
pulses which are converted in to distance signals; the gyroscope detects and meas ures any change in direction.
The GPS signal continues to be received and is used as a reference by the navigation system.
• After the navigation system is calibrated, the arrow will be displayed on the map in the correct position and the
correct direction. To get to this stage, one or two changes of direction of the vehicle may be necessar y. The
navigation system supplies audio commands to the user during this time for any direction changes requir ed. Audio
commands are supplied through the speaker assembly, mounted under the instrument pane l assembly on the
instrument panel lower bracket.
• If the driver does not take a recommended turning point, the navigati on system calculates an alternate route and
supply audio command for that route.
Further:
• Calibration takes longer if the vehicle is driven along a straight road for some distance.
• The vehicle’s position is stored by the processor after the vehicle’s ignition is turned off. The navigation system
requires 30 seconds to shut down properly.
• If the vehicle’s position has been stored previously, the navigation system operates without GPS reception and is
still accurate.
• The vehicle’s position remains in memory after the batter y has bee n disconnected, but only if the navigation system
has been allowed 30 seconds to shut down properly before disconnection.
Navigation System Page 12L–9
Page 12L–9
1.2 Component Layout
The navigation system is provided by Siemens VDO Dayton to Holden specifications. This is a brief description of the
layout and functions of equipment, refer to Figure 12L – 2.
The processor assembly (1) is mounted in th e rear compartment below the rear window panel assembly. The processor
assembly contains a CD–ROM and other components required for the navigation system to operate.
The GPS antenna assembly (2) is mounted on top of the rear window panel assembly with double-sided tape. The
harness is routed through the panel and connects to the processor assembly with connector A139 – X4 (3).
The navigation wiring harness (4) is connected at the processor assemb ly by three connectors, A139 – X1 (5), A139 –
X2 (6) and A139 – X3 (7). T he navigatio n wiring harness leads from the processor assembl y, down the left-hand side of
the vehicle and terminates at the left-hand hinge pillar trim assembly. At this point, the navigation wiring harness is split
into connectors X207 (8), XO1 (9), XO2 (10) and B104 (11).
Connector X207 connects the navigation wiring harness to the bod y harness. Through this connecti on, the navigation
system uses the following vehicle resources:
• X207 pin 3 — constant battery power to the processor in all states. This is the supply of power for the navigation
system.
• X207 pin 2 — supplies a signal to the processor assembly when the vehicle is in use. This is active only whe n the
ignition switch is in the ON or ACC position.
• X207 pin 7 — park lam p relay signal which informs the navigation system when the vehic les headlamps are turned
on. This data is used to control the illumination leve l of the display during da ytime or night-time operation.
• X207 pin 5 — backup lamp signal which supplies a signal to the navigation system when the vehicle is moving in
the reverse. This uses either the backup lamp switch (manual transmission) or the neutral / safety backup switch
(automatic transmission) to supply this signal.
• X207 pin 6 — cluster assembly data, which provides VSS pulses for the navigation system. The navigation s ystem
uses this signal to calculate the speed at which the vehicle is travelling.
• X207 pin 8 — ground.
Connector B104 is attached to the speaker a ssembly (12) by a clip. B104 connects the speaker assembly to the
navigation wiring harness.
Connectors XO1 and XO2 connect the nav igation wiring harness to the cockpit nav igation wiring harness (13). The
cockpit navigation wiring harness contains two separate harnesses of connector XO1 and XO2 which are wrapped
together. This harness is routed behind the instrument panel and attached to the instru ment panel bracing.
The cockpit navigation wiring harness terminates at the navigation display assembly (14), and connects to the display
with connector P6 (15).
The cockpit navigation wiring harness terminates under the instrument panel lower extension side trim with connector
A35 (16).
The remote control assembly with presenter (17) is secured to the front console assembly. The remote control cradle
wiring harness (18) is routed under the presenter, behind the transmission selector and to under the right-hand console
extension where it connects to the cockpit navigation wiring harness at connector A35.
The display assembly is mounted to the radio housing with a bracket. For Sedan and Coupe the display assembly has an
escutcheon (refer to Figure 12L – 2, Item 19) placed in front of this to blend it into the centre instrument console. The
front console cover is modified to allow for the display assembly and escutcheon.

2.5 No Response From Remote Control
No Response From Remote Control
Introduction
The remote control sends signals to the pro cessor assembly in either of two methods. In the first method, with the remote
control removed from the remote control cradle and pointed at the display assembly, the signal is received by the display
assembly, then transmitted through the display wiring harness to the processor assembly. In this case the power to
transmit the signal is from the remote control batteries.
The second method is with the remote contr ol situate d in th e remote control crad le. In this case, signals from the remote
control transmit directly through the remote control cradle and its wiring harness to the processor asse mbly. The power
to transmit the signal from the remote control is provided by the vehicle via the processor assembly and remote control
cradle.
The following conditions exist when the remote control is in operative:
• The navigation s ystem is oper ational, with the title screen on the display
• The navigation system does not respond to commands from the remote control

2.8 Guidance Problems
The processor continuously calculates the vehicle position. When a destination is entered, the processor calculates the
best possible route dependi ng on the user's preferences. If the user does not follow the directions provi ded by the
processor, the processor must recalcul at e another route, then provide the user with new directions. Problems ma y occur
in guidance when the us er does not follow the processor route instructio ns and makes a number of changes in directi ons
before the processor can recal culate the route. The process or eventually calculates the c orrect route, but must be given
some time. In this case, the user has obviously strayed from processor guidance i nstructions; the processor al ways
maintains the correct location of the vehicle.
Condition One – Processor Input Faults
Introduction
With the navigation system operational and in use, incorrect guidance i nstructions ar e given by the processor.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
1 With the navigation system operational and in MAP mode, the scale is not at a level that shows the correct position
of the vehicle. A change of scale may increase the accurac y of the dis played position.
2 If the system has been driven along straight long roads for excessive periods or has been recently disabled, the
navigation system may need calibrating.
3 Checks if the DIRECTION option in the SET I/O ST ATE menu is set to ACT_HIGH.
4 Checks if the processor is receiving an adequate GPS signal to ensure an accurate calculation of the position of
the vehicle. Isolates if the GPS antenna is at fault.
5 Checks if the processor’s internal gyroscope is faulty.
6 Checks if the CD–ROM is out of date.
7 Checks if the processor is receiving VSS. Isolates whether there is a VSS fault or the processor is fault y. If there is
a VSS fault, the check isolates whether it is contained in the navigation system or within the other systems of the
vehicle.
8 Checks for continuity between connectors X207 and A139 – X1. Isolates whether the fault is in the processor or the
navigation wiring harness.

3.4 Read GPS Data
Service personnel commonly suspect bad satellite reception as the cause of poor navigation s ystem perf ormance. GPS
data supplied to the processor is processed every few seconds to confirm the positi on calculated by the map-matching
software is correct. Good GPS data is essential to the system when it is first installed in the vehicle or when the vehicle is
moved from one location to another without the navigation system being active.
Within the navigation processor unit, there is a separate GPS receiver which receives GPS data from the antenna and
transmits calculated data to the processor. If the internal GPS receiver is faulty, the navigation processor must be
replaced.

4.11 Navigation System Calibration
LT Section No. — 000–2
The navigation system requires calibration only if the vehicle has be en moved without the navigation s ystem functioning
or if the vehicle’s battery has been disconnected without allowing the system to shut do wn properly. The navigation
system requires 30 seconds to shut down before disconnection.
Calibration of the navigation system is performed automatically when the vehicle is moving and the navigation system
functioning. Calibration does not need to be performed by the technician, but if the customer is unaware of calibration
requirements, they may believe the system is not functioning correctly.
For the system to calibrate, the following must be performed:
• The navigation system must be functioning.
• The vehicle must be driven unt il the arrow representing the vehicle is correctly aligned with the digital map
displayed on the monitor.
NOTE
The more turns taken during calibration, the
faster the system calibrates.
