Description and Operation

OVERVIEW

The navigation system provides audible and visual route guidance information to enable the driver to reach a desired
destination. The system allows the driver to choose the desired route using minor or major roads and will present 3 routes to
the driver based on user preferences. Directions to hospitals, museums, monuments and hotels are also available. The
navigation computer uses map information stored on a DVD (digital versatile disc) to determine the best route for the journey
and provide the driver with details of directions and approaching junctions.

The navigation system has various levels of user control through the Touch-screen and JaguarVoice system. System volume
adjustment can be made using the ICP (integrated control panel), Touch-screen and steering wheel controls.

There are 3 navigation system variants specific to various markets. On all systems the GPS (global positioning system) signal
is received by the GPS (global positioning system) antenna located in the roof pod antenna module.

The European navigation system includes the TMC (traffic messaging channel) function, which receives traffic information from
an FM antenna integrated into the heated rear window. On a pre-selected route the system will offer re-routing options
depending on traffic conditions.

The Japanese navigation system includes the VICS (vehicle information and communication systems) function. The VICS
(vehicle information and communication systems) supplies 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 an FM antenna integrated into the heated rear window and a VICS beacon located in the LH upper side of the
instrument panel.
The NAS (North American specification) variant does not include any additional traffic information systems.

The navigation system is primarily controlled from the Touch-screen which is located in the center of the instrument panel.
Control signals from the Touch-screen are sent on the MOST (media oriented systems transport) ring to the navigation
computer. The navigation computer uses a dedicated GVIF (gigabit video interface) bus to transmit video signals to the Touch-
screen.

Depending upon the audio system version fitted the navigation audio output signals are sent on the MOST (media oriented
systems transport) ring to the IAM (integrated audio module) or the power amplifier for speaker output.

INTRODUCTION TO THE GLOBAL POSITIONING SYSTEM

The system used to calculate the current position of the vehicle is called the GPS. The system utilizes satellites which are owned by the United States Department of Defense. A total of 24 satellites circular orbit the earth every 12 hours at a height
of 20,000 km (12500 miles), and between 5 and 11 of these satellites can be seen from a single point at any given time. The
orbits are tilted to the earth's equator by 55 degrees to ensure coverage of polar regions. Each satellite transmits radio signals
to provide information about the satellite position i.e. latitude, longitude, altitude, almanac data and an accurate time signal
generated by an on-board atomic clock. Each satellite contains four atomic clocks.
The vehicle needs to receive data from at least four different satellites to give a three dimensional fix on its current position.

As the vehicle moves, this information is continually being updated. The computer determines which satellites are 'visible' to
the system and their current position and relationship to each other. Using this information the computer can account for
positional deviations of the satellites and compensate to enhance the accuracy of the navigation system.

The GPS signal is also known as the PPS (precision positioning signal). PPS (precision positioning signal) predictable accuracy is:
22 meters horizontal accuracy
27.7 meters vertical accuracy
200 nanoseconds time accuracy

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 driver's pre-determined preferences or the default settings in the navigation computer.
The navigation system is accessed from the Touch-screen home menu.
Navigation is initiated by the driver inputting a destination. This can be achieved by:
Entering an address using the Touch-screen
Entering a post code
Choosing a previous destination
Choosing a point of interest from the map disc database
Choosing the home location
Choosing a memory stored location

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.

In addition to the standard navigation system there are two market dependant systems that supply extra information to the
navigation system and the driver. These are:
TMC (traffic message channel) (Europe only)
VICS (vehicle information and communication system) (Japan only)

The TMC (traffic message channel) is a function of the FM (frequency modulation)RDS (radio data system). The system
broadcasts real-time traffic and weather information. Data messages are received and decoded by the TMC (traffic message
channel) integral receiver and processed by the navigation computer. TMC (traffic message channel) messages can be 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. All TMC (traffic message channel) events on the map can be viewed not just the ones on the calculated
route.

TMC (traffic message channel) traffic information systems conform to a global standard that has been adopted by traffic data
gatherers, information service providers, broadcasters and vehicle/receiver manufacturers.

All TMC (traffic message channel) 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 message channel) traffic data is currently broadcast in many European countries.
The VICS (vehicle information and communication system) is broadcast in the Japanese market.
The VICS (vehicle information and communication system) supplies 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 3 routes:

RF (radio frequency) transmission
Infra-red transmission
FM multiplex transmissions
The RF (radio frequency) transmissions are generally transmitted from road side beacons mainly on expressways. The
information transmitted is as follows:
Traffic congestion
Travel time to next intersection
Traffic conditions in surrounding areas and expressway turn offs
Traffic accidents
Speed limits
Lane regulations
Tire change
Parking availability at expressway service areas and parking areas
Infra-Red transmissions are transmitted from road side beacons on major trunk roads. The information transmitted is:
Traffic congestion and travel time
Traffic accidents
Breakdowns
Road works restrictions
Parking availability

FM transmissions are broadcast as part of the FM multiplex broadcasting system from NHK FM stations. Information transmitted is:
Traffic congestion and travel time for wide areas
Traffic accidents, road works, speed limits and lane restrictions for a wide area
Parking availability information
The traffic data is split from the normal FM transmissions by the diversity antenna module.
Selection of 'Navigation' on the Touch-screen home menu and subsequent sub-menu selection sends a control request signal to
the navigation computer on the MOST (media orientated systems transport) ring. The requested control information is
processed by the navigation computer.

If voice guidance is operational the voice signal information is relayed from the navigation computer on the MOST (media
orientated systems transport) ring to either the IAM (integrated audio unit) or Power Amplifier, dependant on equipment level,
for output on the speaker system. The navigation audio output is through the front speakers whilst the background audio, for
example radio or CD (compact disc), is played at a reduced volume on the rear speakers.
The GPS signal is available to the navigation system at all times when the vehicle ignition is switched on.
Navigation user voice commands are made using the JaguarVoice system. The ICM (information control module) processes the
analogue signal from the JaguarVoice switch into a digital signal. The digital signal is passed from the ICM (information control
module) onto the MOST (media orientated systems transport) system to the JaguarVoice control unit which is integral with the
navigation computer.

The navigation computer sends an instruction via the MOST (media orientated systems transport) ring to the IAM (integrated
audio module) to turn on the microphone facility.

The microphone is hardwired to the IAM (integrated audio module). The spoken voice command signals are relayed from the
IAM (integrated audio module) via the MOST (media orientated systems transport) ring to the navigation computer for

NAVIGATION COMPUTER Component Description

The navigation computer is located in the left hand side of the luggage compartment.

VICS (vehicle information and communication system) receiver (Japan only)
TMC (traffic message channel) receiver (Europe only)
JaguarVoice control module

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 inputs from the ABS module, the GPS antenna and the gyro sensor, the computer calculates the vehicle's current position, direction and speed.

The navigation computer houses the DVD (digital versatile disc) drive. The drive is used to read map data from region specific
DVD's. The number of DVD's issued per region varies depending on the amount of information available. The regions are as follows:

Europe (2 versions, Western Europe and Whole of Europe)
NAS (North American specification)
Japan, Middle East, Australia and South Africa

A button, located adjacent to the DVD slot, is provided to eject the DVD from the unit. Prior to ejecting the disc the slot protection has to be slid to the side. If the ignition is on, or the entertainment system is in 1-hour mode, one press of the
button will eject the DVD.
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.

No configuration procedure is required if the navigation computer is replaced. There is no option to calibrate the navigation
computer using the Jaguar approved diagnostic equipment; however in some regions a software download, contained in the
DVD disc, is required before the navigation system becomes operational.
MICROPHONE



A single microphone is used for hands-free operation using the JaguarVoice system. The microphone has an integrated noise
suppression system for hands-free use. The microphone is a standard directional type and is located in the front roof overhead
console. The microphone is hardwired to the IAM (integrated audio module). When replacing the microphone extra care must be
taken to make sure it is fitted into its securing clips for correct positioning and orientation.

GPS Antenna


The GPS antenna passes signals from the GPS satellites to the navigation computer for processing. The antenna is located in

the roof pod and is shared with the DAB (digital audio broadcasting) band L antenna or satellite radio antenna where fitted.
The roof pod is located externally in a central position towards the rear of the roof.

The GPS antenna is designed with 50 ohm output impedance. The navigation computer is fitted with 50 ohm fakra II connectors to ensure compatibility with the antenna. For optimum performance 50 ohm low loss coaxial cable is used between
the antenna and navigation computer.
It is possible for the GPS antenna to lose the signal from the GPS satellites; In hilly or tree lined areas
Built up areas with tall buildings
In multi storey car parks
In garages
In tunnels
On bridges
During heavy rain or 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.

TMC/VICS FM Antenna

Data messages for both TMC (traffic message channel) and VICS (vehicle information and communication system) are received
through the FM antennas and diversity antenna module located in the heated rear window.
VICS Beacon Antenna (Japan Only)



The VICS (vehicle information and communication system) beacon antenna receives infra red and RF (radio frequency) traffic
data signals from road side transmitters. The antenna is connected to the navigation computer which incorporates a VICS
(vehicle information and communication system) receiver.

Touch Screen Display


The Touch-screen is the control interface for the following vehicle systems;
