My issue is with any paired phone. I paired my wifes Blackberry and it has the same beep tone overlayed. I have sinced exchanged the unit and I still has the same issue. I disconnected everything from the unit except what was absolutely nescessary and I still have the issue. I guess it could be something in the car (2007 Milan) interfering with the bluetooth? Not sure. I seem to be one of the few with this issue. Any suggestions?
