Volvo Repair: volvo auto repair, torx screw driver, rear view mirror

Question
I have a rear view mirror that is loose in it's mount and it bounces up and down and vibrates as you drive. The car is a 1996 850 station wagon. Can the cover plate be removed and the mirror tightened to correct this problem? I have never encountered a rear view mirror attached like this before, normally they are glued to the windshield. Thank you for any help you can give me.

Answer
Mike these are fun.  remove the 2 map light covers to access the screws.  Remove the whole assembly out so it will easier to work.  The mirror has a little cover that pops off.  Now using a 30 torx screw driver put it in the black portion of the mirror.  there are 2 screws.  now the fun part.  There are 2 steel rods that need to be placed back into place.  Once you get there let me know and we can go further unless you have figured it out.  Its hard to explain.  Roger
