Radio, Stereo, and Compact Disc: Description and Operation

Overview

The Audio Unit acts as the "processor" for all audio functions. Select audio functions from the front panel. The audio display provides the current audio status. (See the owner's manual for more details.)

The XM receiver passes its signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus. Any open connections in the GA-Net bus circuit will cause audio functions to appear inoperative.

GA-Net Bus Configuration

The GA-Net bus passes audio commands throughout the audio components. These commands include hard button signals, audio/XM selections, and XM station and music title names. Because the entire bus is "daisy chained" between components (see diagram), any open or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. The addition of any audio accessory must maintain the continuity of the GA-Net bus by installing the "Y" cable included with the accessory kit.
