Overview
Speed-sensitive volume compensation (SVC)
23-164Audio System
System Description
The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit, the audio
remote (on the steering wheel), or by using the navigation voice control system. The audio display provides the
current audio status. For vehicles with navigation, additional audio information is available by touching the audio
button on the navigation audio screen (See the owner’s manual and the navigation system manual for more details.).
The XM receiver passes its signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus.
Any open connections in the GA-Net bus circuit causes audio and navigation functions to appear inoperative.
For vehicles with navigation, pressing the open/close switch on the navigation display panel allows access to the CD
slot and PC card.
A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle’s security
system.
Some audio systems are equipped with speed-sensitive volume compensation (SVC). The navigation or audio unit
receives the vehicle speed pulse (VSP) from the ECM/PCM. The system processes the speed input and increases the
navigation or audio system volume level as the vehicle speed increases to compensate for the various interior noises
that occur at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four
settings: SVC OFF, LOW, MID and HIGH that can be adjusted using the navigation or audio unit. The SVC comes from
the factory with the MID setting as the default.
To change the audio unit SVC setting, press the tune folder sound knob repeatedly until the SVC is displayed, rotate
the knob to adjust the SVC to the desired setting (SVC OFF, LOW, MID, or HIGH).
To change the navigation unit SVC setting, press the AUDIO button, and then select the SOUND icon on the navigation
display. Press the navigation display to select the desired setting (OFF, LOW, MID, HI).

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.

the vehicle, see your dealer.
If you need to replace the navigation unit, you can
back-up the navigation data and transfer it to a new
navigation unit. See Save users memory (see page
23-310).
When the battery is disconnected, the internal GPS clock resets to 0:00. The clock resets to the correct
time after the system finishes GPS initialization.
Before disconnecting the battery, make sure you have the anti-theft codes for the audio system 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).
After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10
to 45 minutes.
Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
Before returning the vehicle to the client, enter the anti-theft codes for the audio system and 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 Any time the navigation system loses power, you need
to enter the 4-digit anti-theft code on the navigation
system display. This 4-digit code is located on a small
code 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 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 ECU info diagnostic screen. This allows
you to get 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 or audio unit, make
sure you give the client 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:
