Telematics Muting Logic

The navigation system provides voice control for the audio, the XM, and the CD player. The navigation system uses the GA-Net bus to communicate the voice control commands to the audio unit. When using the TALK/BACK buttons, the front and the rear speakers are muted and you hear the navigation instructions through the center speaker. When using the route guidance (RG), the center speaker provides the navigation sound and the front and the rear speakers continue to play the audio. When using the HFL/AcuraLink, the center speaker and the rear speakers are muted and the front speakers give the telephone sound. When using the HFL/AcuraLink and the RG or the talk back, the rear speakers are muted and you hear the telephone sound and navigation instructions through the front speakers. Muting commands are passed on the GA-Net bus. For more information, see the navigation service information. The outline of the audio interruption function is shown in the following table.
