General Operation
Anti-theft Feature
Symptom DiagnosisSelf-Inertial Navigation Limitations
23-90Navigation System
General Troubleshooting Information
Refer to the Navigation System manual for the
navigation system operating procedures.
The navigation system has a coded theft protection
circuit. Be sure you have the client’s anti-theft security
code before;
Disconnecting the battery
Disconnecting the navigation unit A (17P) and C (12P) connector
Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box
After service, reconnect power to the navigation unit,
and turn the ignition switch ON (II). Enter the 4-digit
anti-theft security codes, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the Navi ECU diagnostic screen (see page 23-139).
Alternatively, you can find the serial number from the
navigation unit in the dash.
When replacing the navigation unit, be sure to give the
client the new anti-theft security code.
Certain circumstances and system limitations can result
in occasional vehicle positioning errors. Some clients
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing clients
about symptoms of the navigation system. The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause some discrepancies between
the vehicle’s actual position and the indicated vehicle
position (GPS vehicle position).
The following circumstances may cause vehicle
positioning errors:
Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface.
– Driving with snow chains mounted.
– Abnormal tire pressure.
– Incorrect tire size.
– Frequent lane changes across a wide highway.
– Continuous driving on a straight or gently curving highway.
Tolerances in the system and map inaccuracies will sometimes limit how precisely the vehicle position is
indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible).
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage.
– Driving on a road with a series of sharp hair-pin turns.
– Driving near a gradual highway exit or transition.
– Driving on one of two close parallel roads.
– Making many 90 degree turns.
– The direction to destination icon or the destination icon shown or the map may be up to several
hundred feet away from the actual location.

Symptom DuplicationService Precautions
System Initialization
23-92 Navigation System
General Troubleshooting Information (cont’d)
If you can duplicate the symptom, compare it to a
known-good vehicle. Only use a vehicle of the same
model, same year, same trim, and same software
version. If you can duplicate the symptom in the
known-good vehicle, then it is a characteristic of the
system.
When the symptom can be duplicated, 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.
– Try to establish if outside interference may be 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 aftermarket electronic devices (vehicle locators, radar detector amps, etc.)
that may be hidden.
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 creating effects unrelated to
the original problem. If you need to replace the navigation unit, inform the
customer that personal information in the navigation
system may be lost. If possible, have the client record
their personal information before the unit is replaced
On ’07-08 models you can back-up the navigation
data and transfer it to a new navigation unit. See save
users memory (see page 23-150).
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 date (which are lost when the ECM/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.
Before returning the vehicle to the client, enter the audio and navigation anti-theft security code, then
enter the audio presets.
Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
If the navigation system loses power (like the battery
was disconnected), the navigation system requires
initialization. Once completed, your system is ready to
use.
This initialization requires the following: Entering the 4-digit anti-theft security code to unlock the system
GPS initialization (may not be needed depending of the length of time the system was without power)
Map matching to align the GPS to a location on the map

Entering Security CodeGPS Initialization
23-93
The system is acquiring its GPS signal.
This could take up to 10 minutes. Engine must be running
Vehicle must be parked outside, away from buildings
Do not move the vehicle at this time
***Wait***
Any time the navigation system loses power, you need
to enter the 4-digit anti-theft code on the navigation
system display. The 4-digit code is located on a small
card that was given to the customer. Enter the 4-digit
code, then select Done.
If the navigation system anti-theft code is missing, use
the interactive Network (iN) to look it up. You will need
the serial number for the navigation unit to do this.
You can view the serial number by entering the
diagnostic mode. Select Unit Check from the main
menu, then the Navi ECU diagnostic screen. This gives
you the serial number without removing the navigation
unit.
The iN may display more than one code for a given
serial number. This is because serial numbers are not
unique. You may have to try more than one 4-digit code.
If no code is shown, or if the code(s) given do not work
in the navigation unit, contact the Automobile Warranty
department. If the code 0000 works, replace the
navigation unit.
When replacing the navigation unit, make sure you give
the customer the new anti-theft security code. NOTE: You must park the vehicle outside with a clear
view of the southern sky.
Depending on the length of time the battery was
disconnected, your system may require GPS
initialization. If it does, the following screen appears:
If this procedure is not necessary, the system proceeds
directly to the Disclaimer screen. During initialization,
the system searches for all available GPS satellites, and
obtains their orbital information. During this procedure
the vehicle should be out in the open with a clear view
of the sky.
