Navigation Computer
The navigation computer is located under the left hand
front seat. The computer is the main component in the
navigation system and receives inputs from the ABS
Unit and the GPS antenna. The navigation computer
contains a solid state piezo gyro which measures the
motion of the vehicle around its vertical axis. The gyro
operates on the principle known as the Coriolis force.
The Coriolis force is the force that appears to accelerate
a body moving away from its rotational axis against the
direction of rotation of the axis. Using the inputs from
the ABS unit, the GPS antenna and the gyro sensor, the
computer calculates the vehicles current position,
direction and speed.
The navigation computer also houses the DVD-ROM
drive. The drive is used to read map data from region
specific DVDs (1 DVD for each of the following
regions: EU, US, Japan and Australia). A button, located
adjacent to the DVD slot, is provided to eject the DVD
from the unit. If ignition is on, or the Entertainment
System is in 1-hour mode, one press of the button will
eject the DVD.
The GPS receiver receives information from between
1 and 8 satellites at any one time. This information is
received from the GPS antenna. The built in GPS
receiver is used for calculating the position (i.e. Latitude,
longitude and height), direction and speed.
The navigation computer uses non-volatile memory to
store settings and configuration information when it is
powered down. This process takes place just before the
computer turns off.
CAUTION: If the unit is disconnected before
the Entertainment System has powered down,
the computer could fail to complete its data
storage. This means that personal settings could
be lost.
For the Japanese market the navigation computer is a
different component. Although it looks identical the
software is specific to Japan market and the part number
is different. The system also has extra components for
the VICS system (a receiver and an antenna). The VICS
system receives allows the vehicle to receive information
about traffic conditions from roadside transmitters and
adjust the navigation instructions accordingly. The VICS
information is received by both a radio link and an infra
red link. For this reason the antenna is located on the
inside of the windscreen.
The navigation computer is connected to the TSD by a
private CAN bus and a dedicated GVIF (Gigabit Video
Interface). The GVIF carries all the video information
to the TSD, while the CAN bus is used for data and
control instructions to and from the TSD.

							GPS Antenna
The GPS antenna is located in a pod which is in the in
the center on the vehicle roof at the rear. The GPS
antenna is connected to the GPS computer by a single
co-axial cable and passes signals from the GPS satellites
to the navigation computers built in receiver for
processing.
It is possible for the GPS antenna to lose the GPS signal
from the GPS satellites in hilly or tree lined areas, built
up areas with tall buildings, multi storey car parks,
garages, tunnels, bridges and during heavy rain/
thunderstorms. When the signal is lost the navigation
computer will continue to give guidance using memory
mapped data from the DVD map until the signal is
restored.
Traffic Message Channel (TMC) Receiver
The Traffic Message Channel (TMC) receiver is located
in the rear RH side of the luggage compartment. The
TMC receiver is connected to the MOST ring and
transmits TMC data to the navigation computer (via the
TSD). The navigation computer then displays this
information on the TSD and also re-routes the navigation
guidance around any traffic hold ups. The TMC data is
received via the FM antenna located in the rear screen
via an antenna amplifier located above the rear tailgate
spoiler.
TMC is available in many European markets.
Vehicle Information and Communication
System (VICS Japan only) Receiver
The VICS system comprises the following components:
•VICS receiver
•VICS Beacon antenna
•VICS RF antenna
The VICS receiver is located behind the Integrated Head
Unit (IHU) in the instrument panel. The VICS receiver
is connected to the navigation computer via a dedicated
link.
The VICS receiver, receives information from the
beacon antenna in the centre of the instrument panel
and the VICS antenna located in the rear screen element.
Navigation SystemLesson 2 – Electrical
211Technical Training (G421304) 
						

							VICS Beacon Antenna
The VICS beacon antenna is located on top of the
instrument panel. The antenna receives infra red and
RF signals from road side transmitters.
NAVIGATION SYSTEM OPERATION
The navigation system receives GPS information via
the GPS antenna. The GPS signals are used by the
navigation computer to calculate the vehicles position.
Once the driver has input a desired destination the
navigation computer can calculate a route, based on the
drivers pre-determined preferences or the default settings
in the navigation computer.
The navigation system is accessed by pressing the
navigation button at the bottom left hand side of the
TSD. The driver will then have the option of on road
navigation or off road navigation.
On Road Navigation
On road navigation is initiated by the driver inputting
a destination. This can be achieved by:
•Typing in and address from the TSD.
•Entering a post code.
•Choosing a pre-entered address from the address
book.
•Choosing a point of interest from a an area.
The driver is then guided to the destination by a scrolling
map display and voice guidance. The display can be
varied by scale and display type.
Off Road Navigation
The off road navigation route comprises a series of way
points which are followed sequentially. Direct point to
point guidance is given to the first way point in the
route. When the vehicle arrives at the first way point
guidance is given to the second way point in the route.
This process continues for subsequent way points until
the final way point (destination) is reached.
The routes are stored in the non-volatile memory of the
navigation computer.
The routes can be entered on the TSD and comprise
way points, Longitude and latitude destination and
previously stored routes.
The different route guidance screens give the user the
information required for direct point to point direction
to the selected destination (guidance mode). The same
guidance screens are also available even when guidance
is not being given (compass mode). All the destination
and guidance information is not shown on the guidance
screens when in compass mode. When the system is in
compass mode with no guidance being given the route
title is ’COMPASS MODE’.

							The 4x4i System uses inputs from other vehicle systems
to display information about suspension and
transmission operation along with navigational
information.
TRAFFIC MESSAGE CHANNEL
(TMC) SYSTEM
The Traffic Message Channel (TMC) is a function of
the FM Radio Data System (RDS). The system
broadcasts real-time traffic and weather information.
Data messages are received and decoded by the TMC
receiver and passed onto the navigation system, which
then delivers them via the navigation system interface.
TMC messages are filtered by the navigation computer
so that only those relevant to the current journey are
displayed, allowing the navigation system to offer
dynamic route guidance - alerting the driver of a
problem on the planned route and calculating an
alternative route to avoid the incident.
TMC traffic information systems conform to a global
standard that has been adopted by traffic data gatherers,
information service providers, broadcasters and
vehicle/receiver manufacturers. TMC information is
received via the normal FM radio antenna.
All TMC receivers use the same list of event codes,
while the location database (on the map disc) contains
both a country-specific set of location codes for the
strategic European road network
TMC traffic data is currently broadcast in many
European countries.
VEHICLE INFORMATION and
COMMUNICATION SYSTEM (VICS
Japan only)
The VICS system supplies the navigation computer with
information to enable the navigation computer to
re-route the navigation guidance or to inform the vehicle
driver of traffic conditions in the vehicles vicinity.
Information is provided to the system through three
routes:
•RF transmission
•Infra-red transmission
•FM multiplex transmissions.
The information is passed to the navigation computer
via the VICS receiver and the IHU
RF Transmission
RF transmission is generally transmitted from road side
beacons mainly on expressways. The information
transmitted is:
•Traffic congestion
•Travel time to next intersection
•Traffic conditions in surrounding areas and
expressway turn offs
