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.

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)

System Description (cont’d)
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 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

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.

Track A sound recording on a CD, tape, or PC Card.
Treble An adjustment to control the volume of the high frequency sounds.
Tuner A component (or part of a component) that receives radio signals and selects
one broadcast from many.
Tweeter A speaker designed to reproduce the higher frequencies (treble) only.
USB Universal Serial Bus. The USB is used for playing the compressed audio files
(MP3, WMA, and AAC) on the external device through the audio unit.
Voice coil A coil of wire wrapped around a tube and then attached to the speaker cone or
diaphragm. When an audio signal is applied, the coil becomes an
electromagnet and interacts with the permanent magnet causing the come or
diaphragm to vibrate. We interpret this vibrations as sound.
Volume control Allows you to control the loudness of the music.
WMA music file Windows Media Audio File. This is an accepted format for music files to be
played on either a CD-R, a CD-RW or a PC Card.
Woofer A speaker that is designed to reproduce low (bass) frequencies only.
XM radio Satellite based radio transmission, which also uses a ground based repeater
network to ensure seamless reception. The channels originate from XM’s
broadcast center, in Washington, DC, and uplink to two satellites. These
satellites transmit the signal across the entire continental United States.
XM receiver The external component that receives and processes the XM signals from the
XM satellites, and terrestrial (land) stations. The audio unit communicates to
the XM receiver over the GA-Net bus.
