95 Camry Wagon Rear View Mirror Removal/Replacement
 

I'm attempting to remove & replace the rear view mirror (the day/night toggle tab is broken, which causes the mirror to shake at times). It appears as though the mirror pop-fits onto a swivel, similar to the free-standing base that say a GPS would pop onto. Any assistance would be appreciated.

I was able to locate the cover at the roof, which houses the screws retaining the mirror. Help is no longer required.
