The optional navigation system provides voice control for the audio, XM, and CD player. The GA-Net (audio unit)
communicates the voice control commands. When using the TALK/BACK button, the audio is muted on all speakers
and you hear navigation sound on the front channels. When using the navigation or route guidance (RG), the front
speakers provides the navigation sound. The GA-Net bus passes the muting commands. For more information, see
the navigation section. The outline of the interruption function is shown in this table.

The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include navigation touch screen and hard button signals, audio/XM selections by voice, 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.
