OK, I give up, how does one go about replacing the interior rear view mirror on the top of the windshield frame???? Or just replacing the mirror and glass?

The mirror just pops off. Grab it by the steel mounting rod and pull. If you change the mirror the new one will just snap on. If you want to change the reflective glass take a small screwdriver and pop the plastic front off the mirror. The glass will fall out and can be replaced. The plastic front piece then just snaps back on.
