NAVIGATION SYSTEM
87-4 DESCRIPTION AND OPERATION

Inputs and Outputs
In addition to the vehicle sensor and the antenna inputs, the navigation computer also receives the following:
lA permanent battery feed from the passenger compartment fusebox, to power the navigation function.
lAn ignition switched battery feed from the passenger compartment fusebox, to power the navigation, radio and
CD functions when the ignition switch is in positions I and II.
lAn illumination power feed for switch illumination and LCD backlighting when the exterior lights are on.
Navigation computer outputs consist of those for the ICE system speakers and to the auxiliary CD autochanger, where
fitted.
Security Code
The navigation computer is programmed with a five digit security code selected from numbers 1 to 7. If the battery or
the navigation computer are disconnected, the code is requested on the LCD the first time the navigation computer
is switched on after reconnection; this also occurs if a different removable panel is fitted.
The code is entered using the appropriate multifunction buttons. The navigation computer automatically starts to
operate when the fifth digit of the correct code is entered. If an incorrect code is entered, CODE is displayed on the
LCD to prompt another entry attempt. If an incorrect code is entered three times in succession, WAIT is displayed on
the LCD and the unit is disabled for approximately 60 minutes. If the navigation computer is switched off, the
remaining disabled time will resume when the power is restored.
Automatic Volume Control (AVC)
The AVC feature automatically increases and decreases the audio volume with increases and decreases of vehicle
road speed. The AVC feature, also known as the GAL setting, uses the vehicle speed signal from the ABS ECU and
can be turned off or adjusted to start at a different vehicle speed. The GAL setting is accessed through the User Menu
and can be set to between 0 and +15, where 0 is off and +1 to +15 progressively increase the vehicle speed at which
AVC starts to operate.

NAVIGATION SYSTEM
DESCRIPTION AND OPERATION 87-5
System Settings Menu
The system settings menu provides access to features that can be changed to suit market and personal preferences
and to navigation system operating features. On European systems, the system settings menu also includes
computer games and a currency converter. While the navigation computer is in the navigation mode, the system
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.
lMEASURING UNIT – Allows the route guidance distances displayed on the LCD to be switched between metric
and Imperial units.
lANNOUNCEMENT ETA – Allows the route guidance ETA announcement to be switched on and off.
lCALCULATE EURO – Provides access to a currency converter.
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).

NAVIGATION SYSTEM
DESCRIPTION AND OPERATION 87-7
Sensor Check
1Call up the SENSORS screen on the LCD:
lIf the navigation CD-ROM has not been installed before, press and hold multifunction button 1 then press
multifunction button 10.
lIf the navigation CD-ROM has been installed before, use the garage menu as detailed above.
2Drive the vehicle forwards a short distance at a speed greater than 2.5 mph (4 km/h) and ensure the road speed
counter on the SENSORS screen starts to increment.
3Select reverse gear and ensure the direction arrows on the SENSORS screen point rearwards.
4Ensure the GPS data on the SENSORS screen is displayed and updated.
NOTE: The GPS data will randomly display a GPS MODULE FAILURE message. This is not a fault condition, and
no action need be taken, provided the GPS data switches between the GPS MODULE FAILURE message and
actual GPS data.
5Exit the SENSORS screen:
lIf the navigation CD-ROM has not been installed before, press and hold multifunction button 1 then press
multifunction button 10.
lIf the navigation CD-ROM has been installed before, press the Nav button.
Calibration Routine
1Park the vehicle outside in an area clear of high buildings, trees etc.
NOTE: The more open the surrounding area is, the faster the system will acquire sufficient GPS satellite signals to
begin calibration. To minimise the calibration time, the vehicle should not be moved again until the calibration
ride.
2Turn the ignition switch to position II. If the navigation computer does not come on, press the navigation
computer ON button.
3If necessary, use the navigation computer multifunction buttons to enter the security code.
4Turn the ignition switch to position 0 and remove the ignition key.
5Press the navigation computer ON button.
6Call up the SENSORS screen on the LCD:
lIf the navigation CD-ROM has not been installed before, press and hold multifunction button 1 then press
multifunction button 10.
lIf the navigation CD-ROM has been installed before, use the garage menu as detailed above.
7Turn the LH rotary control to minimum volume.
8Wait for 30 minutes. If necessary, the vehicle can be left unattended and locked.
NOTE: Land Rover recommend a minimum of 30 minutes be allowed to elapse in order to ensure that only a short
distance need be driven to achieve calibration.
9After the 30 minutes have elapsed, ensure the navigation computer LCD shows a GPS almanac figure of 27 or
higher.
10Start the vehicle engine and allow to idle.
11Install the navigation CD-ROM.
12Wait until the navigation computer LCD prompts for a language to be selected. Turn the RH rotary control to
scroll through the options, highlight the required language and press the RH rotary control to select.
13The navigation computer LCD will prompt for a voice to be selected. Turn the RH rotary control to scroll through
the options, highlight the required voice and press the RH rotary control to select.
14Wait until the navigation computer LCD advises "language has been loaded OK". Press the RH rotary control to
confirm the language and voice selections.
15The navigation computer LCD will default to the CALIBRATION RIDE screen and should show the
CALIBRATION RIDE CAN START message. The GPS data and the road speed counter will also be shown.
16Drive the vehicle over a road route approximating that shown below (it is not necessary to copy the route
exactly). Calibration is complete when the navigation computer LCD switches to show DESTINATION & POI
and the satellite graphic. If all the pre calibration ride conditions were complied with, calibration is typically
achieved within 3 miles (5 km) and usually occurs when the vehicle returns to the start point. However,
calibration may be achieved earlier in the journey and, if it is, there is no need to complete the remainder of the
calibration route.
