Telematics Muting Logic
Vehicles with navigation provides voice control for the audio, the XM, the CD player, and the RES functions. The GA-Net (audio unit) communicates the voice control commands. When using the TALK/BACK or route guidance (RG) or AcuraLink, all speakers reduce the audio output and you hear the navigation instructions through the center speaker. When using HFL, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound. The RES headphones are not impacted by HFL, AcuraLink, RG (Route Guidance), or TALK/BACK playing through the front or center speakers. B-CAN bus passes the muting commands. For more information, see the navigation section. The outline of the audio interruption function is shown in the following table.
