Overview

Audio 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).
