Hello. I own a 2002 honda crv and yesterday after leaving my car parked in front of a clients home for four hours I returned to find my rearview mirror just lying on the front floorboard. It was completely attached when I'd parked the car and although I rarely touch or move the mirror it did not appear to be loose in any way prior to its falling off. The part of the mirror that was attached to the windshield looks as if it has cracked glass on it which someone said is probably just the glue that had been used to attach the mirror. However, the area on the windshield itself where the mirror was attached looks as if the glass is cracked as well. It sort of looks like when a bb goes through glass, only cracking/shattering in a small area. Is that just the glue as well or could this small square of glass actually be shattered?
