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.

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.

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.

TestBook/T4 Diagnostics
No serial diagnostic link is provided with the CARiN III navigation system, so TestBook/T4 cannot interact with the
system.
Vehicle Position
If the vehicle’s battery has been disconnected, or if the vehicle has been transported to a new location on another
vehicle (e.g. by trailer or train), the navigation system will require up to 15 minutes to identify the new position. Entering
the vehicle’s position manually, reduces this delay. To enter the vehicle's position manually:
1Highlight and select Information.
2From the information menu, scroll down to the next screen and highlight and select Vehicle position.
NOTE: If the correct CD is in the navigation computer, the country is automatically entered. If you have travelled
to a new country, a new CD may be needed.
3From the vehicle position menu, highlight and select City, then use the typewriter menu to enter the vehicle’s
position (town, road, etc.) in the same way that you would enter a destination.
4Once the town and road names are entered, the navigation computer asks for a junction. This is the name of the
road that forms the next junction ahead of the vehicle.
5Highlight and select Junction, then enter the name using the typewriter, or select the correct road name if a list
of names is displayed. Crossing the junction will be highlighted. Drive the vehicle in the direction of the junction
and press the rotary controller when you reach the junction.
NOTE: The vehicle position menu provides a street map facility which enables you to check your vehicle’s current
position and assists in identifying the name of the next road junction.
Provided that the information entered into the computer is correct, the navigation system requires approximately 1
minute to determine the vehicle's position.
Navigation and Trafficmaster
Road navigation and off-road navigation are accessed from the main menu by highlighting and selecting the
appropriate title with the rotary controller. In both modes of navigation, this brings up a safety notice on the display
unit. Pushing the rotary controller again accepts the safety notice and replaces it with a menu screen, which is the
entry point for operation of the navigation function. The Trafficmaster function only operates in the road navigation
mode, and is activated and de-activated by pushing and holding the menu switch for more than 0.5 second. When
activating the Trafficmaster function, the system returns to the navigation mode if the menu switch is not released
within 1.5 seconds.
Refer to the Owner Handbook: Navigation, CARiN III & Traffic Master, Publication Part No. LRL 0586ENG for full
details of how to operate the road navigation, off-road navigation and Trafficmaster functions.
