I love my Boxster, with one exception.......That crappy manual review mirror.  When I adjust it at night by flipping the toggle on the bottom of the mirror, it reduces the glare, but creates a shadow effect of the lights that I find anoying.
Has anyone reto fit an electro-chromatic mirror in their Boxster?  Does Porsche even have that as an option??  I'm sure I will not be able to find a mirror woth the Boxster shape (so you don't see the head rest/roll bar) in the mirror.  
 I have noticed there is a very fine wire in the center of the windshield (antenna???) that runs a direct path of the OEM mirror base.  Any problems with negative effects of a auto dim mirror on the radio?  Just a thought.
