Overview
The audio unit acts as the " p r o c e s s o r " for all audio functions. Selection of the audio functions can be done f r o m 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 w i t h the navigation option, additional audio information
is available by touching the audio button. (See the owner's manual for more details.)
Each audio component passes its audio signal to the audio unit. In addition it communicates w i t h the audio unit via the
GA-Net bus. Any open connection in this circuit w i l l cause audio and navigation functions to appear inoperative.
The system includes an active noise control system to cancel some of the vehicle noise. It use a sine-wave shaped
sound output to cancel l o w frequency noise. T w o microphones detect the l o w frequency sound, and the system
outputs a canceling sound t h r o u g h the audio speakers.
