10. Turn the ignition switch to LOCK (0).
11. Start the engine in the known-good vehicle, and
then do steps 4 thru 10 on the known-good vehicle.
12. Compare the number of stations received in steps 6 and 9 in the client’s vehicle with the number of
stations received in the known-good vehicle.
 If the number of stations received is the same, or within 10 %, the audio unit’s tuner performance
is OK. The problem may be atmospheric
conditions, multi path interference, or other
obstructions to the radio signal.
 If the customer’s vehicle receives fewer stations by at least 10 %, go to step 2 of poor AM or FM
radio reception of interference, with navigation
(see page 23-196), wit hout navigation (see page
23-199). SRS components are located in this area. Review the
SRS component location (see page 24-11).
Also review the precautions and procedures (see page
24-13) in the SRS section before doing repairs or
service.
NOTE:
 Put on gloves to protect your hands.
 Take care not to scratch the dashboard and related parts.
 Lay a workshop towel under the parts when working on them to protect the face panel from scratches or
other damage.
 Do not work in a dusty or dirty place.
 Discharge static electricity from your body before and during the work.
 Do not touch the circuit board(s) with your bare hands.
 Do not work with dirty hands.
 Be careful not to fold the flat plate cable.
 Do not touch the terminal connector of the flat plate cable with your bare hands (If you have touched it,
wipe it off thoroughly.).
 Eject all the discs before removing the audio unit to prevent damaging the CD/DVD player’s load
mechanism.
 If you are replacing the audio unit, write down the audio presets (if possible), and enter them into the
new audio unit.

23-266Navigation System
General Troubleshooting Information
Refer to the navigation system manual for the
navigation system operating procedures.
The navigation system and audio unit have a coded
theft protection circuit. Make sure you have the anti-
theft security code before:
 Disconnecting the battery.
 Disconnecting the navigation unit connector A (24P) and C (8P).
 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 to ON (II). Enter the 4-digit
anti-theft security code, 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 ECU Info diagnostic screens (see page 23-305).
Alternatively, you can find the serial number on the
underside label which is located on the navigation unit
in the trunk.
When replacing the navigation unit, be sure to give the
customer the new anti-theft security code.
Certain circumstances and system limitations will result
in occasional vehicle positioning errors. Some client’s
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 client’s
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 discrepancies between the
vehicle’s actual position and the indicated vehicle’s
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
– Very bumpy roads
 Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle’s 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 GPS cannot detect the vehicle’s position or
elevation during the following instances:  For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
 When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside
parking structures or large trucks.
 When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the
vehicle. The GPS antenna requires a clear
unobstructed view of the sky.
 When there is no satellite signal output (signal output is sometimes stopped for sate llite servicing).
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.

ÎGA-Net Bus Configuration
Muting Signal Logic
23-282Navigation System
System Description (cont’d)
Navigation unit
Accessory
(CD changer etc.)
XM receiver
USB Adapter
The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include audio/XM selections by voice, and XM station and music title names. Because the entire bus
is daisy chained between components (see diagram below), any open or short in the GA-Net bus harness will cause
any or all of these functions to become inoperative. The addition of any factory audio accessory must maintain the
continuity of the GA-Net bus by installing the Y cable included with the accessory kit.
The audio muting logic is orchestrated by the navigation unit. The navigation unit determines what audio source has
priority to use the speakers.
The priority of the audio sources is as follows:
HandsFreeLink has the highest priority, followed by, navigation, and finally the radio/CD player. The priority is passed
by HandsFreeLink to the navigation unit by dedicated mute wires. The navigation mute signal is passed to the stereo
amplifier.
The navigation unit temporarily disables the voice control buttons, but allows guidance to be heard. In addition, the
navigation unit suppresses the output from the XM receiver, disc pl ayer, or other audio accessories.
When the navigation system sends out a voice route guidance command, the rear speakers are muted, and the
navigation voice is heard in the front speakers.
When the navigation voice control system and HandsFreeLink is use, the rear speakers are muted, and the navigation
voice prompts are heard from the front speakers.
