23-6 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).
The navigation system allows voice control for the audio, XM, PC card, and CD player. The GA-Net (audio unit)
communicates the voice control commands. When using the navigation TALK/BACK button, the audio is muted on all
speakers and you hear navigation sound on the front channels. When using the navigation or route guidance (RG), the
front speakers provides 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 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. 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.

Audio GlossaryItem Definition
23-9
GA-Net The GA-Net allows the audio unit to communicate with all the audio and
navigation components in a vehicle. If there is an open in the GA-Net or
components, components or the entire audio and navigation system may
appear inoperative.
GB (Gigabyte) A unit of memory or disk storage equal to billion bytes (1000 million bytes).
HDD Abbreviation for hard disc drive. They are sensitive to heat and it is not
recommended that they be used in the PC card slot for playing audio files.
Hertz (Hz) The unit of frequency equal to one cycle per second (cps). One kilohertz (kHz)
equals 1,000 cps; one megahertz (MHz) equals 1 million cps.
Integrated amplifier A component that combines a pre amp and a power amp into a single unit. A
receiver combines an integrated amp and a tuner into a single unit.
Jewel case The hard plastic case that contains a compact disc or DVD. Always use a jewel
case to prevent scratches on the underside of a CD or DVD.
LCD (Liquid Crystal Display) A type of digital display that changes reflectance or transmittance when an electrical field is applied to it.
Memory Circuitry or devices that hold information in electrical or magnetic form, such
as the AM/FM radio presets.
MB (Megabyte) One million bytes. Written as 1 MB. Megabytes are used as a measure of digital
storage space. For example, a CD can hold 650 MB.
Mic An abbreviation for microphone. For vehicles with navigation, the microphone
accepts navigation voice commands to control audio and navigation functions.
MP3 music files MP3 is an audio coding format. MP3 is a popular audio compression format on
the Internet and computers. CDs and PC Cards with these files can be played on
some vehicle’s audio system.
Mute When the navigation gives guidance, the front speakers are muted (no music).
When you use the voice control system, all of the speakers are muted.
Noise Unwanted random sounds like buzzing, hiss, pops, static, whine, etc.
PC card The slot used for playing MP3 and WMA music files. The PC Card is usually a
combination of a small flash card in a PCMCIA adaptor that slides into the slot.
The ATA, SD, and compact flash types of cards have been tested up to 1 GB.
PCMCIA A computer standard for the slot that the PC card slides into. Another term for
the PC card slot.
Processor The part of an audio device that performs tasks/calculations. In the audio unit
the processor handles muting to allow the navi to speak its voice commands,
and the decoding/playback of the sound files etc.
Radio A head unit that combines a tuner, a preamplifier, and often a power-amplifier.
Route guidance (RG) Spoken voice used for turn-by-turn navigation from the audio speakers.
SCF (Cold Start Fix) screens These screens are displayed if the system requires a GPS initialization. The vehicle should be moved outside into an open area away from buildings/power
lines.
Stereo A recording of at least two channels where you can hear sound or music from
the left or right side.
SD (Secure Digital) card This compact type of memory card allows for fast data transfer and has built-in security functions. SD cards have a small write-protection switch on the side.
Shield A metallic foil or braided wire layer surr ounding conductors which are
designed to prevent electrostatic or electromagnetic interference (noise) from
external sources such as buzzing, or popping sounds heard on the speakers.
Speaker (Loudspeaker) A device that converts electrical energy into acoustical energy (sound).
Speed-sensitive volume
compensation (SVC) The SVC increases the audio volume to compensate for increased interior noise
when the vehicle drivers at freeway speeds.
Subwoofer A loudspeaker made to reproduce the lowest audio frequencies, about 25 Hz to
125 Hz.
