Radio, Stereo, and Compact Disc: Description and Operation

System Description

Overview

The audio system features a non-premium and premium option. The premium audio system features a 360-watt AM/FM/CD audio unit with 7 speakers including a subwoofer. The non-premium audio system features a 120-watt AM/FM/CD audio unit with either 6 or 4 speakers. For '08 model, the non-premium audio system including ANC features a audio unit with 7 speakers including a subwoofer. In addition, '08 all models are supported of playback function of compressed audio files recorded on CD-R/RW.

The audio unit acts as the processor for all audio and video signals (RES). You can select the audio functions from the front panel, the audio remote (on steering wheel), or by using the navigation voice control system. The audio display provides the current front and rear audio status. For vehicles with the navigation option, additional audio information is available by touching the audio button (See the owner's manual for more details).

The audio disc (6CD) changer output can be directed either to the front or to the rear. For vehicles with the navigation option, pressing the open/close switch on the navigation display panel accesses the audio disc changer.

With the premium audio system, an stereo amplifier powers the 6 speakers and a subwoofer, otherwise the speakers are powered directly by the audio unit. For '08 non-premium audio system, additional subwoofer is powered directly by the active noise control unit.

Each audio component passes its audio or video signal to the audio unit. In addition, they communicate with the audio unit via the GA-Net bus. Any open connection in this circuit will cause audio and navigation functions to appear inoperative.

The navigation system provides voice control for the front/rear audio, XM, CD player, and RES functions. The GA-Net(audio unit) communicates the voice control commands. When the navigation unit is giving voice guidance, only the front speakers are muted. When using the voice control system, all speakers are muted, but not the RES headphones. The GA-Net bus communicates the muting commands. For more information, see the navigation section.

A security signal is daisy-chained between the audio, RES, and navigation components for integration into the vehicle's alarm system.

Active Noise Control (ANC) System

The system includes an active noise control system to cancel some of the vehicle noise. It uses a sine wave sound output to cancel noise developed during cylinder cancel operation. This occurs in the 1,400-2,400 rpm range. Two microphones detect the low frequency sound, and the system outputs a canceling sound through the audio speaker.
