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.

 Auxiliary accessories may be played on the audio unit using the auxiliary input.
1. Turn the ignition switch to ON (II).
2. Turn on the audio unit or navigation unit and connect an aux iliary accessory to the auxiliary
input jack.
3. Check the volume operation.
Operation is normal at this time.
Go to step 4.
4. Make sure the auxiliary accessory volume to max.
Go to step 5.
Raise the auxiliary accessory volume is set to
high. Make sure the audio unit volume is turned
down before retesting.
5. Substitute a known-good aux iliary audio accessory
and/or auxiliary stereo cable, and recheck.
Original auxiliary audio accessory or
auxiliary stereo cable is faulty.
Go to step 6.
6. Turn the ignition switch to LOCK (0). 7. Remove the auxiliary jack assembly (see page
