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).

Overview

System Description
The navigation system is a highly sophisticated, hybrid locating system.
The navigation unit uses global positioning system (GPS) satellite signals, internal yaw and vehicle speed inputs, and
a map database to show where the vehicle is and to help guide you to a desired destination.
The navigation unit’s GPS receiver receives signals from the GPS, a network of 24 satellites in orbit ar ound the earth.
By receiving signals from several of these satellites, the navigation system can determine the latitude, l ongitude, and
elevation of the vehicle.
Signals from the system’s yaw rate sensor (inside the navigation unit) detects turns, and the ECM/PCM vehicle speed
pulse (VSP) and reverse signal enable the system to keep track of the vehicle’s speed and direction of travel. The
advantage of this hybrid system is that the system can track your position if either the GPS signal or the vehicle speed
signal is missing. For instance, when in a tunnel (no GPS), the speed signal is used to update your position on the map.
Alternately, while the vehicle is being transported on a ferry, GPS signals can show the vehicle position on the map as
it crosses the water.
The navigation system uses the location, direction, and speed information to display the appropriate map and
calculate a route to the destination entered. As you drive to a destination, the system provides both visual and audio
guidance. Audio guidance is sent to the audio unit, and an RGB graphics color signal is sent to the navigation display.
This navigation system also has voice recognition that allows voice control of most of the navigation, and audio
functions. The voice control switches (navigation TALK and navigation BACK buttons on the steering wheel) activate
the voice control system. The microphone on the ce iling receives your voice commands. For more information on this
feature, consult the navigation owner’s guide.
The illumination signal is used by the navigation unit to automatically switch the display mode between the Night and
Day display modes. When the headlights are on, the dash brightness control setting full brightness overrides the Night
display mode, and allows a daytime navigation display with the lights on.
When the navigation system is giving voice guidance commands, the front speakers are muted. When the voice
control system is being used (navigation TALK button pressed), all of the speakers are muted.
The internal GA-Net II bus passes information back and forth between the navigation display, the navigation unit, and
the audio system components. The information passed on this bus are touch button commands, audio muting signal,
audio (radio and XM), and any open in these bus lines can affect the navigation system or other audio accessory
operation.
The clock on the navigation display is set and maintained by the navigation unit. The time is automatically adjusted for
daylight savings, and time zone changes while driving. The time can be adjusted in setup.
Additional information is available about the navigation components following the System Diagram. A glossary of
terms that are used throughout this section follows the detailed information.
The Navigation System Manual in the glove box covers all of the system functions and settings. Use this as a resource
when evaluating a customer concern.
The Comm.Bus connects the HFL and the navigation unit.
If a POI phone number is available, the navigation unit sends the phone number (on the calcurate route to screen) to
the HandsFreeLink control unit for dialing.

This screen is for factory use only, and should always
be set to OFF. Occasionally the DEMO setting is turned
ON when vehicles are being used at Auto Shows or
similar events. Turning this feature on, allows the
navigation system to automatically follow a route to a
destination when the vehicle is stationary. The Speed
changes the speed of the demo mode. This diagnostic allows you to independently test the
microphone and the navigation TALK and BACK
buttons. They are used to activate the voice control
system. The microphone is located near the map light
in the roof console. It is directional, and works only with
the voice coming from the driver’s seat.
Press the navigation TALK button on the steering wheel, wait unit you hear a beep, and in a normal
voice say ‘‘testing’’. The TALK indicator on the screen
should momentarily turn green, and the text Now
Recording... should appear in yellow. If the talk
indicator shown on the screen does not briefly turn
green, check the wiring from the steering wheel
navigation TALK button to the navigation unit. If there
is no Mic Level movement when you speak, then you
should check the wires running from the microphone
in the roof console to the HandsFreeLink control unit
and the navigation unit. If the wires are OK, the
microphone must be faulty; replace the microphone
located in roof console (see page 23-358).
PressthenavigationBACKbuttononthesteering wheel. This should cause the Cancel indicator on the
screen to momentarily turn green. If it does not
briefly turn green, check the wiring from the steering
wheel navigation BACK button to the navigation unit.
