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).

Audio Glossary
Item Definition
23-167
NOTE: All items may not apply to this vehicle. See the owner’s manual for more information.
Active noise cancellation The active noise cancellation system cancels some of the vehicle noise. This occurs in the 1,500 2,400 rpm range. Microphones detect the low frequency
sound, and the system outputs a canceling sound from the audio speaker.
AM (Amplitude Modulation)
Amplifier A device that increases the level of a signal by increasing the current or voltage.
Antenna A device used to send or receive electromagnetic waves thr ough the air.
ATA (PC Card) A type of card that has been tested for use in playing WMA, and MP3 music files in the PC Card slot. Sizes of up to 1 GB have been tested.
Audio remote switch The switches on the steering wheel that control the audio system.
Auxiliary jack Allows the customer to use a portable audio device to i nput audio recordings.
Balance A control that changes the relative volume of the left and right channels.
Band A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses.
Bass An adjustment for the low frequency sounds of around 160 Hz and below.
Byte A unit of storage for computer files and memory. A CD holds approximately 700 million bytes.
Cassette Audio or video magnetic tape container having two reels. Customers can insert it for play back
Compactflash Astandardforsmall-size(3x4cm),memorycardsusedinmobilecomputers, PDAs, digital cameras. Compact flash memory cards are available in size of
32 MB up to 4 GB or more and can be played in the audio PC slot. Sizes above
1 GB have not been tested.
CD (Compact Disc) A 4.5-inch plastic disc containing digital audio recording that is played optically on a laser equipped player. Never use discs with a paper label. In a hot vehicle,
labels can curl up and jam the unit.
CD (audio disc) changer CD player that can store and play more than one CD. Two types are available. Some units accept CDs fed into the changer one at a time, and others accept a
magazine (with CDs stacked in a container).
CD player A com ponent designed to play compact disc recordings using a laser optical
pickup. The signal from a CD player usually requires amplification.
Decibels (db)
Distortion Inexact repr oduction of an audio signal caused by playing music at levels the
audio system cannot handle.
Dolby (noise reduction) A processing system developed by Dolby Laboratories that reduces the background noise on recording media. The result is a cleaner playback from the
audio system.
DUET A serial data communication line used for sub display.
DVD (Digital Versatile Disc) A 4.5-inch CD-like format used for storing movies with digital audio and video features. The DVD-A format is a DVD format designed for DVD audio systems.
Some vehicles can play DVD and DVD-A formats.
Equalizer A device that changes the relative volume of individual frequency bands to suit personal tastes of the listener.
Fader The control that adjusts the relative volume levels of front and rear speakers in a four-speaker system.
Format To prepare a PC Card to receive files this function is done on a PC. Always choose either FAT or FAT32, as the NTFS format is not accepted by the system.
Pick the default sectors for the format method selected.
FM (Frequency Modulation) The form of modulation used for radio and television sound transmission in most of the world. Less prone to interference than AM. The FM broadcast band
in North America covers roughly 87.7 to 107.9 MHz.
(cont’d)
The type of transmission used in the standard radio broadcast band from 530 to 1710 kHz.
A method of measuring sound or radio signal strength received by the audio unit antenna.
