I searched all over this site and could not find a reference to my problem. Where I live my cell phone gets no signal. Whenever I leave home my cell captures a signal about the same location each day. What I've noticed is that if I have the radio on I hear, what I think, is the cell phone signal through the audio system. It sounds exactly the same every time, a beep, beep, followed with more beeps closer together. I'm sure that it's the cell phone because I once heard the same beeps on a radio at work when I turned on my cell. So-- if anyone can else has had this proplem I'd like to know. My intention is to mention it to Acura next time I take the MDX in for service.
