Navigation System
Symptom Troubleshooting (cont’d)
NOTE:
• Always check the connectors for poor connections or
loose terminals.
• Before troubleshooting, make sure you have the
navigation system anti-theft code.
• After troubleshooting, re-enter the anti-theft code,
and re-initialize the navigation system.
• Check for aftermarket accessories that use the same
power circuit. A feedback can cause this problem.
1. Remove the key from the ignition.
Go to step 2.
Intermittent failure. The system is OK at this
time. Check for loose or poor connections.
2. The vehicle may have been used as a
demonstration vehicle at an event like an auto
show. In these events, power is often jumpered to
the navigation system so that the ignition key is not
needed in the vehicle. At the end of the show, the
jumper wire may not have been removed. Check
the navigation unit connector C (8P) for a ‘‘non-
factory’’ jumper wire in series with the factory
cable.
Remove the jumper wire, and re-test. Return
the jumper wire to Tech Line.
Go to step 3.
3. The navigation display or navigation unit may have
been jumpered to allow the navigation system to
run without the ignition key.
Go to step 4.
Go to step 5.
