I understand there is a setting where I can tell it to mute with a call, but I can't find it. Can anyone direct me to that setting? If the audio doesn't mute, it seems pretty stupid.

how do you set it to mute? i have been unable to find that setting. i received a call yesterday that i could barely hear over the audio, since it didn't mute. my stock stereo did, and i would assume the avic would, i just can't find it in the settings.
