When using the HFL/AcuraLink®, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound. When using the HFL/AcuraLink® and the RG (Route Guidance) or the TALK/BACK buttons, 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 information. The outline of the audio interruption function is shown in the following table.
