2Press and hold multifunction button 3, then press multifunction button 5 to display the garage menu.
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.
To quit the garage menu, 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.
17After calibration is achieved, return to the dealership, park the vehicle and stop the engine.
18Turn the ignition switch to position I.
19Use the system settings menu to set the navigation computer to local time and the required units of measure:
aPress the Nav button.
bTurn the RH rotary control to scroll through the displayed menu, highlight TIME and press the RH rotary
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.
