Navigation system (Description): Description and operation (page 6 of 6)

4 Ensure 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. 5 Exit the SENSORS screen: l If the navigation CD-ROM has not been installed before, press and hold multifunction button 1 then press multifunction button 10. l If the navigation CD-ROM has been installed before, press the Nav button.

Calibration Routine 1 Park 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.

NOTE: On NAS Freelanders, when the security system RF receiver is active it disrupts the GPS satellite signals. To allow the navigation system to operate, the RF receiver is deactivated when the ignition is on. During calibration, ensure the ignition remains on and that the vehicle is not parked next to a Freelander with an active RF receiver. 2 Turn the ignition switch to position II. If the navigation computer does not come on, press the navigation computer ON button. 3 If necessary, use the navigation computer multifunction buttons to enter the security code. 4 Call up the SENSORS screen on the LCD: l If the navigation CD-ROM has not been installed before, press and hold multifunction button 1 then press multifunction button 10. l If the navigation CD-ROM has been installed before, use the garage menu as detailed above. 5 Turn the LH rotary control to minimum volume. 6 Wait for 30 minutes. If necessary, the engine can be started.

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. 7 After the 30 minutes have elapsed, ensure the navigation computer LCD shows a GPS almanac figure of 27 or higher. 8 Start the vehicle engine and allow to idle. 9 Install the navigation CD-ROM. 10 Wait 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. 11 The 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. 12 Wait until the navigation computer LCD advises "language has been loaded OK". Press the RH rotary control to confirm the language and voice selections. 13 The 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. 14 Drive 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. 15 After calibration is achieved, return to the dealership, park the vehicle and stop the engine. 16 Turn the ignition switch to position I.
