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).

The navigation system allows voice control of the audio, XM, PC card, and CD player. Voice control commands are
communicated on the GA-Net (audio unit). When using the navigation TALK/BACK button, the audio is muted on all
speakers and you get navigation sound on the front channels. When using the navigation or route guidance (RG), the
front speakers give the navigation sound and the rear speakers continue to play. For more information, see the
navigation section. The outline of the interruption function is shown in this table.

The audio unit can play digital music from portable audio players, USB drive, etc. When the device is plugged into the
USB adapter. The audio unit uses the GA-NET to allow you to control the device from the audio unit when searching
and playing the files. Not all players and player functions work with the USB adapter. Please see the owner’s manual
for more information.
The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XM
station and music title names. Because the entire bus is daisy chained between components (see diagram), any open
or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. Naturally the
addition of any audio accessory must maintain the continuity of the GA-Net bus by installing the Y cable included with
the accessory kit.
