Ok then, where is the microphone for the onstar telephone? I thought what was decsribed above was that ( it looks like a round microphone the size of a quarter in the headliner just above driver's seat)! Thanks EWILL.
Everyone thinks that thing is a microphone, it kind of makes me laugh but whatever.
The microphone is sometimes on the side of the overhead console, sometimes it is built into the bottom of the rear view mirror.
If your mirror has a small square thing sticking down with lines accross it, that is the microphone.
The console ones are as described above, just on the left side of the overhead console near the visor.
Don't talk into the microphone, it is made to work with your head pointed straight at the windshield. You can confuse the VR functions if you talk right into it. Sometimes we tell customers to talk away from it and it seems to work better for them.
Mine has also been making noise Intermittently since I've owned my lade, if I hear it I flick it with my finger and it shuts up for a while.
Does anyone know how much this little part costs if you wanted to replace it yourself?
