Following the advise of a BMW NA tech rep I snapped the microphone grill out of the headliner and removed the microphone so I could peel off the foam tape covering the mic. After reinstalling everything my hands free operation worked 100% better. now people can hear me when I talk without my having to shout or repeat everything I say several time. Its a quick free fix that really works.Originally posted by Doug K:
I don't know if this is the same problem as yours. Everyone was complaing they could't hear me but I could hear them fine. They all said they heard a sound like air blowing thru an open window. The dealer replaced the mic in the headliner and even took the foam baffling out. Still no good! then one day will driving and talking on the phone I addjusted the center vent to blow on me cause it was hot in the car. Bingo; the person on the other end of the phone said it now sounded perfect and loud. The air was blowing on the mic causing interference. maybe this will help you.
