Muting Logic

On vehicles with navigation, the system provides voice control for the audio system and the XM radio. The navigation system uses the GA-Net bus to communicate the voice control commands to the audio unit. When using the navigation TALK/BACK button, the audio is muted on all speakers and you hear navigation sound on the front speakers. When using the navigation or route guidance (RG), the front speakers provides the navigation sound and the rear speakers continue to play the audio. For more information, see the navigation and the HFL sections. The outline of the muting logic is shown in this table.
