HI, my 2004 Avy has the Onstar mic over the drivers head in the headliner (at least I assume it's the mic), and it always buzzes- actually sounds like something spinning almost like an electric fan with the blades dragging on something... It does it all the time when the truck is running. Any ideas? I do have an aftermarket stereo- Pioneer with Nav, Bluetooth, backup cam, DVD... Not sure if that has anything to do with it...
