My 2004 XFC (Coupe) had an "AUTO DIMMING" inside rearview mirror and my 2005 XFR (Roadster) does not.
Question Number One...Was the mirror dropped on ALL 2005 versions or JUST on the Roadster??
Question Number Two...I don't recall seeing any wiring to the XFC mirror (like I see on my Denali and my Mazda). Is it self-contained battery operated??
Question Number Three...IF...it is battery operated (not hard wired) and one was mounted on a roadster would the bright sunlight make it operate all the time like headlights shinning on it would??? (which would consume the battery very quickly when the top was down).

 

I don't know all the answers but i believe it was dropped for 2005 on all models.

 

~ as for the self dimming rear view mirror...

all 04's had the self dimming mirror standard.

but it was not available on any 05' crossfires.


~ my guess is... a cost saving issue for chrysler.

 

From experience...2004 Limited (the only flavor that year)...when I installed LED's to brake and turn signals, and re-wired the back-up to strobes, the auto-dimming function quit. I traced it back to the body control computer, which "tells" the rear-view mirror when to dim or not. It does this by sending 12V signal (hi = Dim, <12v no-dim), so that dimming is off when you shift into reverse...Idiot computer figures bulb is "out" so it inhibits dimming. I had to put 12V on input "manually" by routing 12vdc through a switch I installed in map light housing. Now the mirror dims as it should, automatically, based on light coming in to front and rear photoeyes. The electronics to control dimming is in the mirror housing, but the 12VDC to enable it comes from body computer. Hope that helps...ctsemicon "Dad's out in the garage playing with his toy again".

 

So the mirror is "Hard-Wired" and I just missed the Wiring??
