1. GENERAL DESCRIPTION

The Occupant Information Navigation System (navigation system) fitted to the MY 2003 VY Series Sedan and V2

Series II Coupe vehicles is adapted from the Siemens VDO Dayton MS 5000 Navigation System. The MS 5000 has

been modified to Holden specifications for easy vehicle installation. The navigation system is a production option

and is fitted by Holden B y Design (HBD).

The navigation system uses three principal technologies:

• The navigation processor uses the vehicle speed signal (VSS) and an internal gyroscope.

• Global Pos it io nin g S ystem (GPS).

• Digital road mapping.

The navigation system consists of the following components:

• Proce ssor 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 harness (8)

The following modifications are made to the floor console cover assembly to accommodate the navigation system:

• Holes are drilled in the floor console cover assembly so that the navigation remote control assembly and

presenter can be fitted.

• The f loor c ons ol e c o ver as s em bl y is c ut to s p ec if ic atio n to al lo w f or the ins t al lat io n of the nav igat io n d is pl ay

assem bly.

NOTE: Although there are obvious interior trim and body shape differences between the Sedan and Coupe, the

navigation system remains the same for both except for the harness lengths and harness clips.

VEHICLE SPEED AND DIRECT ION

The veh icle spe ed sensor and the gyroscope work together to provide direct ion and s peed. I n conjunc tion with the

position signal received from the GPS, the vehicle speed sensor and gyroscope provide the processor with the

necessary information to produce vehicle navigation to the user.

GLOBAL POSITIONING SYSTEM

The GPS is a series of 27 satellites (nominally 24) which orbit the earth at an altitude of 20 372 km. The signals

from f our satellites m ust be r eceived b y a GPS rece iver to get an ac curate thr ee-dim ensional pos ition. If only three

satellit e signals are re ceived a posit ion is attaine d, but with reduced ac curacy. The pos ition calc ulated by the GPS

receiver is acc ur ate to bet w een 30 a nd 1 00 metr es. GPS r ec ept io n ma y be interrupte d, es pec i al ly due to t he natur e

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

• If the GPS antenna assembly and the position of the satellites are not favourable due to the satellite’s orbit

DIGITAL ROAD MAP

The digital road map is supplied b y Siemens VDO Da yton. The map is contained on a Com pact Disc (CD–ROM),

which is read b y the proces sor assem bly. This CD mus t be inserted into the pr ocessor as sembly for the s ystem to

work. Update versions of the map are available from Holden Spare Parts Organisation (HSPO).

1.1 GENERAL OPERATION

NOTE: For inf ormation on t he navigat ion s yst em operatio n, refer to the Satellite Navigatio n Handbook Supplem ent

supplied with the navigation system.

The navigation system works 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. This position is translated onto the digital road map

and shown o n the n aviga tion dis pla y in the f orm of an ar row. Initi ally, the vehic le m ay not be s ho wn in its exac t

position, as the navigation system may not be calibrated.

• The user can now enter a destination using the navigation system menus. The remote control, which can be

used whil e i n its cr ad le or p oint ed a t th e dis p lay, is use d to n a vig ate t hr oug h th e n av igat io n system m enus . The

map screen highlights the route to be taken.

• The navigation system begins calibration automatically when the vehicle moves. The VSS provides electrical

pulses which are converted into distance signals; the gyroscope detects and measures any change in direction.

The GPS signal continues to be received and is used as a reference by the navigation system.

• After the na vigation s ystem is calibrat ed, the arro w will be dis pla yed on the map i n the correct position and t he

correct direction. To get to this stage, one or two changes of direction of the vehicle may be necessary. The

navigation system supplies audio commands to the user during this time for any direction changes required.

Audio commands are supplied through the speaker assembly, mounted under the instrument panel assembly

on the instrument panel lower bracket.

• If the driver does not take a recommended turning point, the navigation 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 vehic le’s posit ion is sto red by the proces sor after the v ehic le’s ign ition is turn ed off . T he navigati on s ystem

requires 30 seconds to shut down properly.

• If the veh icle ’s posit ion h as been s tored previ ousl y, the na vigat ion s ystem operat es with out G PS rec eptio n and

still be accurate.

• The vehicle’s position remains in memory after the battery has been disconnected, but only if the navigation

system has been allowed 30 seconds to shut down properly before disconnection.

1.2 COMPONENT LAYOUT

The navigation s ystem is provided by Siem ens VDO Dayton to Holden specif ications. This is a brief description of

the layout and functions of equipment, refer to Fi gure 12L –2.

The processor assembly (1) is mounted in the 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 G PS antenna assem bly (2) is mounted on top of the rear window pan el asse mbly with doub le-sid ed tape. T he

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 assembly by three connectors, A139 – X1 (5),

A139 – X2 (6) and A139 – X3 (7). The navigation wiring harness leads from the processor assembly , 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 body harness. Through this connection, 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

when the ignition switch is in the ON or ACC position.

• X207 pin 7 — park lamp relay signal which informs the navigation system when the vehicles headlamps

are turn ed on. This dat a is used to c ontrol the i llumination level of the displa y dur ing da ytim e or night-tim e

operation

• X207 pin 5 — back-up lamp signal which supplies a signal to the navigation system when the vehicle is

moving in the reverse. This uses either the back-up lamp switch (manual transmission) or the

neutral / safety back-up switch (automatic transmission) to supply this signal.

• X201 pin 6 — c luster ass em bl y data, which pro vides VS S puls es f or the navigat ion s ystem . The navi gation

system uses this signal to calculate the speed at which the vehicle is travelling.

• X201 pin 8 — earth.

Connector B104 is attached to the speaker assembly (12) by a clip. B104 connects the speaker assembly to the

navigati on wirin g har nes s.

Connector s XO 1 and XO2 c onnect th e navigat io n wiring harn ess to the cock pit n avigatio n wiri ng harnes s (1 3). T he

cock pit navigat ion wiring h arness c ontains two se parate har nesses of connector XO1 and XO 2 which are wrapped

together. This harness is routed behind the instrument panel and attached to the instrument panel bracing.

The cockpit navigation wiring harness terminates at the navigation display assembly (14), and connects to the

displa y with connec tor 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. The display assembly has an

escutcheon (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.

assembly does not have the nutserts required for the attachment of the presenter mounting wedge. Two nutserts

and scre ws ar e used to att ac h the pr ese nter mounting wed ge, r ef er to F ig ure 12L –8, t o th e f loor co ns ol e assembly.

The nutserts can be used from the previous console assembly or new nutserts can be ordered.

3.10 NAVIGATION SYSTEM CALIBR ATION

LT Section –

The navigation system requires calibration only if the vehicle has been moved without the navigation system

activate d or if the vehic le’s batter y had been dis connected withou t allowing th e system to shut down properl y. T he

navigation system requires 30 seconds to shut down before disconnection.

Calibrat ion of the n aviga tion s ystem is per form ed auto m aticall y when t he ve hicl e m oves and the navi gation system

activated. Calibration does not need to be performed by the technician, but if the customer is unaware of

calibration requirements, he/she may believe the system is not functioning correctly.

For the system to calibrate, the following must be performed:

• The navigation system must be activated.

• The vehicle must be driven until 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.

4. SYSTEM DIAGNOSIS

Diagnostic tables contained in this Section, list both t echnical problems and comm on faults found due to im proper

use of the navigation system. 4.1 WIRING DIAGRAM and 4.2 CONNECTOR CHART should be used with the

diagnostic tables to fault-find the navigation system.

It is advantageous to read the Satellite Navigation Handbook Supplement supplied with the navigation system

before performing diagnosis on the system.

NOTE: If the proc essor ass em bly needs t o be r em oved or disc onnec ted f rom the veh icle p ower s uppl y, ensu re the

processor assembly has shut down completely. The red LED on the processor assembly extinguishes when the

processor assembly is shut off. Allow approximately 30 seconds after the ignition is turned off for the processor

assembly to shut down.

PREREQUISITES

Safety Requirements

When operating the navigation s ystem as part of any of the Steps in the diagnos is charts, ensure tha t fingers and

limbs are clear of moving parts.

4.7 GUIDANCE PROBLEMS

The proc es s or c ontin uously c alcul ates th e veh ic le posit ion. When a destinati on is enter e d, t he process or c alculates

the best pos sible rout e depending on the user's preferences. If the user do es not follo w the directions provided b y

the processor, the processor must recalculate another route, then provide the user with new directions. Problems

may occur in guidance when the user does not follow the processor route instructions and makes a number of

changes in directions before the processor can recalculate the route. The processor eventually calculates the

correct route, but must be given som e time. In this case, the user has obviously strayed from processor guidance

instructions; the processor always maintains the correct location of the vehicle.

5.4 READ GPS DATA

Service p ersonnel com monly susp ect bad sate llite recepti on as the caus e of poor navigation s yst em perform ance.

GPS data s uppl ied to t he pr ocess or is pr ocess ed every fe w seco nds to co nf irm the pos itio n calc ulat ed b y the m ap-

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 sy stem being active.

W ithin the n avigation process or unit, there is a separa te GPS rece iver which r eceives GP S data fr om the antenna

and trans m its calc ulated data to the pr ocess or. If the internal GP S rece iver is f aulty, t he na vigat ion pr ocess or mus t

be replaced.

RECEIVER STATE DESCRIPTION COMMENT

3D POSITION 3D data on the location of

the vehicle is available

when the system

receives data from four or

more satellites.

In this condition, the satellite icon on the guidance screen is

GREEN. This is the normal condition.

2D POSITION 2D data on the location of

the vehicle is available

when the system

receives data from three

or more satellites.

No geographic height can be determined in this mode. Positional

accuracy is reduced.

The satellite icon on the guidance screen is RED. This is not the

normal condition, but indicates poor or reduced reception.

TRACKING Data from one satellite

has been received by the

system.

This condition is normally encountered when the system is first

powered up. The GPS receiver is in this mode for up to 10

minutes depending upon reception conditions.

The satellite icon on the guidance screen is RED.

SEARCH SAT The system has a valid

almanac and is searching

for satellites.

This condition is normally encountered when the system is first

powered up. The GPS receiver is in this mode for up to 10

minutes depending upon reception conditions.

The satellite icon on the guidance screen is RED.

REC ERROR The system does not

receive sat ell ite sig nal s. This condition usually occurs if the GPS antenna is not

connected or the cable is damaged. If the GPS antenna and

cable are serviceable, the GPS receiver is faulty and should be

replaced.

The satellite icon on the guidance screen is RED.

COM ERROR The GPS receiver is not

providing any data to the

navigation proc es sor.

Internal communication between the GPS receiver and the

navigation proc es sor is not po ssi ble.

5.5 READ ERROR MEMORY

This represents the READ ERROR MEMORY

screen. The RETURN field is automatically

highlighted to return to the START MENU when the

OK button on the remote control is pressed.

The self-diagnosis function of the processor stores

error events to its internal memory. The errors

detected may be due to internal (processor) or

external (environmental or vehicle) conditions. You

may need to view this screen when asked by a

technical consultant during fault diagnosis.
