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)

The type of transmission used in the standard radio broadcast band from 530 to 1710 kHz.

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 is used for playing WMA and MP3 music files in the PC card slot.

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.

Bluetooth Audio

Allows the customer to play audio recordings stored on their cell phone through the audio system.

Byte

A unit of storage for computer files and memory. A CD holds approximately 700 million   bytes.

Compact flash

A standard for small-size (3 x 4 cm), memory cards used in mobile computers, PDAs, and 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.

CD

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 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 component designed to play compact disc recordings using a laser optical pickup. The signal from a CD player usually requires amplification.

CSF (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.

db (Decibels)

A method of measuring sound or radio signal strength received by the audio unit antenna.

Distortion

Inexact reproduction of an audio signal caused by playing music at levels the audio system cannot handle.

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.

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, the entire audio and navigation system may appear inoperative.

GB (Gigabyte)

A unit of memory or disk storage equal to one billion bytes (1000 million bytes).

HDD (External)

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.

HDD (Internal)

Abbreviation for hard disc drive. Some audio-navigation units use an HDD to store navigation software, map data, customer information, and music. The HDD replaces the navigation DVD.

Hz (Hertz)

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.

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 (Microphone)

An abbreviation for microphone. For vehicles with navigation, the microphone accepts navigation voice commands to control audio and navigation functions.

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 navigation system 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

Spoken voice used for turn-by-turn navigation from the audio speakers.

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.

SD module

Some audio-navigation units use an SD module to store navigation software, map data, and customer information. The SD module replaces the navigation DVD.

Shield

A metallic foil or braided wire layer surrounding conductors which are designed to prevent electrostatic or electromagnetic interference (noise) from external sources such as buzzing or popping sounds heard on the speakers.

Loudspeaker

A device that converts electrical energy into acoustical energy (sound).

SVC (Speed-sensitive volume compensation)

The SVC increases the audio volume to compensate for increased interior noise when the vehicle is driven at freeway speeds.

Subwoofer

A loudspeaker made to reproduce the lowest audio frequencies, from about 25 Hz to 125 Hz.

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 jack

See USB port.

USB port

Allows the customers to play data such as input audio recording from portable audio devices (such as i-pod) or data from USB flash memory. The USB is used for playing the compressed audio files (MP3, WMA, ACC, etc.) on the external device through the audio unit.

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 D.C. 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.
