Radio, Stereo, and Compact Disc: Description and Operation
System DescriptionOverview
The audio unit acts as the "processor" for all audio functions. Selection of the audio functions can be done 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.)
Each audio component passes its audio signal to the audio unit. In addition it communicates 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 6CD changer output can be directed to the audio unit.
The XM can be output to the audio unit.
