control to select. Press the + or – multifunction button to adjust the time in 30 minute steps. Select the 24
hour clock and confirm by pressing the OK multifunction button.
cIf metric units of measure are required, go to step e) (the navigation computer defaults to metric units of
measure).
dIf Imperial units of measure are required, turn the RH rotary control to scroll through the displayed menu,
highlight MEASURING UNIT and press the RH rotary control to select. Turn the RH rotary control to
highlight IMPERIAL and press the RH rotary control to select.
ePress the Nav button to return to the destination menu.
20Calibration is complete. The navigation system is ready for use.
NOTE: The accuracy of the system will automatically be fine tuned when a further journey is made, but this is not
required as part of the calibration procedure.
NOTE: In European countries, the territory will have to be set the first time the navigation system is used, and the
first time a destination in another country is selected. The first time the navigation system is used or a destination
in another country is selected, a map is displayed with the default/current territory highlighted. To change the
territory: Press the RH rotary control to display the territory list; turn the RH rotary control to scroll through the
list and highlight the required territory; press the RH rotary control to confirm the selection.

NAVIGATION SYSTEM
87-14 DESCRIPTION AND OPERATION
Description
General
Where fitted, the CARiN III and Trafficmaster system combines a satellite navigation system (CARiN III) with a real-
time traffic information system (Trafficmaster).
The satellite navigation system provides computer generated audible and visual route guidance information to enable
the driver to reach a desired destination. The system allows the driver to choose between road navigation and off-
road navigation, and to incorporate waypoints. Road navigation also allows the driver to choose between using minor
or major roads and the quickest or shortest route. Directions to hospitals, museums, monuments, hotels etc. are also
available. The computer uses map information stored on a CD-ROM to determine the best route for the journey and
provide the driver with details of directions and approaching junctions. The current position of the vehicle is
determined using a combination of vehicle sensor inputs and the Global Positioning System (GPS).
The Trafficmaster system displays live traffic flow information on the road navigation map screens. Traffic speed is
indicated on the maps by colour coded roads and arrows. The traffic flow information is relayed from a network of
sensors covering motorways and trunk roads. Data from the sensors is updated on a three minute cycle, 24 hours a
day, 365 days a year.
The navigation system consists of the following components:
lNavigation computer
lGPS antenna
lDisplay unit
lSwitch pack
lNavigation speaker
lTrafficmaster monitor ECU
lTrafficmaster antenna
Navigation Computer
The navigation computer is located in a bracket under the RH front seat, immediately behind the CD autochanger.
The navigation computer contains all the hardware and software required for control of the navigation system,
including the GPS receiver and a solid state piezo gyro. Using the gyro, and inputs from the GPS antenna and the
vehicle K bus, the navigation computer determines the vehicle’s current position, direction and speed.
The navigation computer also houses a CD-ROM drive. The drive is used to read map data from country specific CD’s
and also to load software into the computer. A button, adjacent to the CD slot, is provided to eject the CD from the
unit. If the ignition is on, one press of the button will eject the CD. If the ignition is off, two presses are required, one
to wake up the system and the second to eject the CD. Access to the CD-ROM drive is from the rear of the RH front
seat.

DESCRIPTION AND OPERATION 87-15
Navigation Computer
The Navigation computer is delivered pre-loaded with operating software, 2 languages and the Off Road navigation
software. The 2 pre-loaded languages are:
lUK English (Female)
lGerman (Male)
Software loading can be achieved at any time by inserting a software CD into the CD-ROM drive. The navigation
computer compares the version of software on the CD with that currently loaded. If the software version on the CD is
a later version it automatically loads the new software. The status of software loading is shown on the display unit.
On completion of software loading, the CD is automatically ejected. The user is prompted to remove the CD and
confirm. The computer then resets and restarts with the new software.
