BOSE uses microphone feedback in some of their stereos in "select" vehicles. These are placed inside the car I believe. Hmmm....maybe this weekend I'll go "car shopping" and see if I can find where they place their microphone(s). I just went to their website, they call it "Audiopilot Noise Compensation Technology".
