settings menu can be accessed by pressing the Nav button. Using the RH rotary control, the following features can
be selected and adjusted:
lTIME – Allows the navigation system clock to be set to local time as opposed to the Greenwich Mean Time (GMT)
transmitted from the GPS satellites. The local time setting is necessary for correct navigation on routes with time
restrictions and for Estimated Time of Arrival (ETA) calculations. The time can only be adjusted in 30 minute
steps.
lSAVE POSITION– Allows the current vehicle position to be saved and allocated a name in the navigation
destination memory.
lGAMES – Provides access to a selection of computer games.
lLANGUAGE– Allows the navigation system language and voice (where applicable) to be changed.
lANIMATIONS– Allows the LCD animations to be switched on and off.

User Menu
The user menu provides access to further features that can be changed to suit personal preferences. While the
navigation computer is in navigation, radio or CD modes, the user menu can be accessed by pressing and holding
the tone button for more than 2 seconds. The user menu is displayed over two screens, which can be toggled between
using the

multifunction button. Using the appropriate multifunction button or the RH rotary control, the following
settings can be selected and adjusted:
Screen 1
lGal – Automatic volume control setting (see above).
lTel – If a handsfree telephone system is connected to the navigation computer, allows either mute (telephone
mute mode) or audio signal (telephone conversation via the ICE speakers) to be selected.
lLcd – The LCD can be set to appear negative, positiveor automatic. In automatic, the display will be positive or
negative, depending on the setting of the exterior lamps.
lLed – A Light Emitting Diode (LED) in the display can be set to off or blinking. When set to blinking, the LED
flashes when the navigation computer is switched off.
lM/S – Radio reception can be set to Stereo, Mono or Auto, to suppress interference and reflections and so
optimise reception. Stereo is for exceptionally good reception conditions. Mono is for poor reception conditions.
In auto, the normal setting, the navigation computer automatically switches between stereo and mono depending
on reception conditions.
Screen 2
lNav – Sets how audio navigation instructions are delivered. In onl, other audio sources are suppressed and only
the navigation instruction is output to the speakers. In mixed, the volume of any other audio source is reduced
and the volume of the navigation announcement is the same as the original audio source +/– 6 dB (adjustable).
In independ, the audio source and navigation announcement can be set to independent volume levels.
lAux – Used to switch auxiliary CD AF connections between Aux mode on and Aux mode off. If no CD
autochanger is installed, an external cassette or CD player can be connected to the navigation computer and
powered by switching on the auxiliary CD AF connections.
lCmp – Allows a compass to be shown on the LCD when route guidance is not active.
lBeV – Used to adjust the signal tone volume. Signal tones sound to confirm storage confirmation etc. and can
be set between 0 (quiet) and +5 (loud).

The garage menu contains the following, which can be accessed using the RH rotary control:
lCALIBRATION RIDE – Used to calibrate the navigation computer, to enable route navigation.
lGPS INFO– Provides functional test of antenna by checking GPS reception. If functioning correctly, displays the
number of satellites being received, the date, time (Greenwich Mean Time) and the type of positional fix currently
possible.
lCALIBRATION– Allows vehicle specific calibration data to be entered, e.g. tyre size. Also allows current
calibration to be deleted prior to re-calibrating.
NOTE: Only known calibration data should be entered. The navigation computer cannot make route
calculations if incorrect data is entered.
lSENSORS– Allows wheel speed, reverse gear and gyro sensor inputs to be checked.
lVERSION– Displays navigation computer hardware and software details.
lSPEECH TEST– Performs a test of the navigation computer audio output.
lMODULE TEST– Performs a test routine on the internal components of the navigation computer.
lDEMO – Allows a route navigation demonstration to be run.

Calibration
Calibration is required after initial installation or replacement of the navigation computer. It may also be necessary
after repairs to system wiring and if route navigation becomes inaccurate or fails to operate. If the navigation computer
contains an existing calibration, this must be deleted, using the garage menu, prior to running the new calibration
routine. The sensor inputs should also be checked before running the calibration routine.
