Thanks Mark. It's nice to read something that's actually useful. That's rare on this site.

How are the rear view mirrors not reusable?

My thought would be that it is equipped with a breakaway mount. Some engineer is probably worried that once removed you have damaged or bent the retainer. Once you have done that the lawyers begin to tell the manufacturer that it no longer meets OE standards.
