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.

Audio
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.

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 through 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 input 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
Compact flash

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 component designed to play compact disc recordings using a laser optical
pickup. The signal from a CD player usually requires amplification.
Decibels (db)
Distortion
Inexact reproduction 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.
The type of transmission used in the standard radio broadcast band from 530 to 1710 kHz.
