I have an 05 Outback LSV (no tower). Weather has been terrible and have only been out once. I have been playing with the mirror in the garage to figure out where to put it. The dealer is telling me to throw away the "spacer" and to take it on and off each time you use it. (need it off to put on cover or get in garage). Doesn't seem right.

Where do people place the mirror? On the center window or the drivers window? Facing "up or down"? Do you take it off to get in a garage or to cover? Do you use the spacer? Am I missing something obvious?
