Radio, Stereo, and Compact Disc: Description and Operation

Audio System Description

Overview

The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit buttons (on the center panel) or the audio remote switch (on the steering wheel)*. The audio display provides the current audio status. The audio unit also supports playback function of compressed audio files (MP3/WMA) recorded on CD-R/RW.

There is an auxiliary jack (AUX) in the center panel*. The system will accept auxiliary audio input using a 3.5 mm stereo miniplug.

The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio presets (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.

A security signal is daisy-chained between the audio and vehicle components and integrated into the vehicle's security system.

Speed-sensitive volume compensation (SVC)

The audio system is equipped with speed-sensitive volume compensation (SVC). The audio unit receives the vehicle speed pulse (VSP) from the ECM/PCM. The system processes the speed input and increases the audio system volume level as the vehicle speed increases to compensate for the 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 audio unit. The factory default setting is MID (see the owner's manual for more information).

USB adapter

The audio system supports the external compressed audio files input using a USB adapter. The audio unit is supporting GA-Net address and commands for the USB adapter unit. While connecting the USB audio device to the USB adapter, the audio unit can control the USB audio device. Also, the audio unit can provide power to the USB audio device through the USB. Connect the USB audio device using the USB adapter cable located in the glove box (see owner's manual).

NOTE: Not all players and player functions work with the USB adapter. See the owner's manual for more information.
