System Description: Overview: Notes

The audio unit acts as the processor for all audio functions. You can select the audio functions from the front panel, the audio remote switch (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 navigation, 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.

With the premium sound system, an audio amplifier unit powers the speakers, otherwise the speakers are powered directly by the audio unit.

The 6CD changer output can be directed to the audio unit.

The XM radio plays through the audio unit.

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