2005-08 ACCESSORIES AND EQUIPMENT Navigation System - RL
Clean the screen with a soft, damp cloth. You may use a mild cleaner intended for eye glasses or
computer screens.
SYMPTOM DUPLICATION
When the symptom can be duplicated, verify that it is not a characteristic of the system. Review the

navigation manual and compare it to a known-good vehicle (with the same software and database),
under the same conditions. If the symptom is not the same as the known-good vehicle, follow the self-
diagnostic procedures and the appropriate troubleshooting procedures.
When the symptom does not reappear or only reappears intermittently, ask the client about the

conditions when the symptom occurred.
Always ask the client to demonstrate the problem.

Try to establish possible user error or misunderstanding of the system.

Try to establish if outside interference may have been the cause.

Try to duplicate the symptom under the same conditions the client experienced.

Vibration, temperature extremes, and moisture (dew, humidity) are factors that are difficult to

duplicate.
Inspect the vehicle for after-market electronic devices (vehicle locators, amps, radar detectors,

etc) that may be hidden.
NOTE:

SERVICE PRECAUTIONS

If the navigation unit needs to be replaced, inform the client that personal information in the

navigation system will be lost. If possible, have the client record their personal information before the
unit is replaced.
On '07 and later models you can back-up the navigation data and transfer it to a new navigation unit.

See save USERS MEMORY , audio system and navigation system.
Before disconnecting the battery, make sure you have the anti-theft codes for the audio and the

navigation system, and write down the audio presets. Also obtain any PGM-FI or transmission DTCs
and freeze frame data (which will be lost when the PCM loses power).
When the battery is disconnected, the internal GPS clock is reset to "0:00". The clock will reset to the

correct time after the system finishes GPS initialization.
After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take

from 10 to 45 minutes.
Verify map matching.
Before returning the vehicle, enter the audio system and navigation system anti-theft security code,

then enter the audio presets.

When interchanging navigation DVD/parts during diagnosis.
When troubleshooting navigation system problems, ensure that
the known-good vehicle is the same software version year and
model as the vehicle being serviced. Mixing incompatible
navigation DVDs or other system components can delay the
troubleshooting process by causing side effects unrelated to the
original problem.
