INTRODUCTION TO THE GLOBAL POSITIONING SYSTEM
The system used to calculate the current position of the vehicle is called the GPS. The system utilizes satellites which are owned by the United States Department of Defense. A total of 24 satellites circular orbit the earth every 12 hours at a height
of 20,000 km (12500 miles), and between 5 and 11 of these satellites can be seen from a single point at any given time. The
orbits are tilted to the earth's equator by 55 degrees to ensure coverage of polar regions. Each satellite transmits radio signals
to provide information about the satellite position i.e. latitude, longitude, altitude, almanac data and an accurate time signal
generated by an on-board atomic clock. Each satellite contains four atomic clocks.
The vehicle needs to receive data from at least four different satellites to give a three dimensional fix on its current position.
As the vehicle moves, this information is continually being updated. The computer determines which satellites are 'visible' to
the system and their current position and relationship to each other. Using this information the computer can account for
positional deviations of the satellites and compensate to enhance the accuracy of the navigation system.

NOTES:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval Program is in operation, prior to the
installation of a new module/component.
Navigation Diagnostic Screen Access

PINPOINT TEST A : POOR SATELLITE RECEPTION www.JagDocs.com
PINPOINT TEST H : NO NAVIGATION VOICE GUIDANCE TEST
CONDITIONS DETAILS/RESULTS/ACTIONS H1: CHECK ALL AUDIO OUTPUT SYSTEMS 1 Check audio output across all systems. Is there sound output across all systems? Yes
GO to H2. No
GO to H3. H2: CHECK VOICE GUIDANCE SOFT KEY 1 Check navigation screen menu, voice guidance soft key is not set to OFF position. Is the voice guidance soft key set to OFF position? Yes
Set the voice guidance soft key to ON position.
Re-check the system
No
GO to H3. H3: VOLUME LEVEL CHECK 1 Check the volume level is not set too low. Is the volume level set too low? Yes
Increase the volume level and re-test vehicle.
No
Refer to electrical circuit diagrams and check integrity of amplifier and speaker system wiring harness
and connectors.
GO to H4. H4: NAVIGATION VOICE ONLY NOT AUDIBLE
NOTE: Only the navigation voice cannot be heard. 1 Press the 'Navigation voice repeat' soft key. After the navigation voice repeat soft key is pressed, can voice still not be heard even though it has
become louder? Yes
Check and install a new Navigation Control Module (NCM) as required. Refer to the new
module/component installation note at top of DTC Index.
No
Operation is normal.
PINPOINT TEST I : NO RESPONSE TO PRESSING NAVIGATION MENU TEST
CONDITIONS DETAILS/RESULTS/ACTIONS I1: NO RESPONSE TO PRESSING NAVIGATION MENU
NOTE: 15 minutes are required for the program to update. If the engine is accidentally turned OFF, start the engine
again, and wait for 15 minutes. 1 Check that the engine was not turned 'OFF' during a navigation software update. Was the engine turned 'OFF' during a navigation software update? Yes
Check the correct map disc is inserted into the Navigation Control Module (NCM). Start the engine and
allow to idle for 15 minutesTurn the engine 'OFF', and then start the engine again.Verify that the
navigation screen displays. Navigation was in the program update mode.
No
GO to I3. I2: NO RESPONSE TO PRESSING NAVIGATION MENU 1 Check that the engine was not turned 'OFF' after inserting the new map disc. Was the engine turned 'OFF' after inserting the new map disc? Yes
Check the correct map disc is inserted into the Navigation Control Module (NCM). Start the engine and
allow to idle for 15 minutesTurn the engine 'OFF', and then start the engine again.
No
GO to I3. I3: NO RESPONSE TO PRESSING NAVIGATION MENU Has a fault been identified with the map disc?
Yes
Replace the map disc.
Re-check the system for 'Map display is incomplete'.
No
Check and install a new Navigation Control Module (NCM) as required. Refer to the new
module/component installation note at top of DTC Index.
