Anyone noticed a blue haze at the bottom of the autodimming mirror when the car gets really hot inside? I have a windshield blind and tinted windows, but i always get that. Does this hurt the lifespan of my autodimming mirror?
I can't say anything about the tC mirror, but I had a similar experience with a mirror in my old Z3. You see, they did not come with the autodimming mirrors. I bought one and fashioned a holder for it. Because I was in a hurry, I wired it so that it was on all the time unless I hit the switch on the bottom side of the mirror. I found that the hazing as you saw it happened more when the mirror was left on over night.
Doubt that helps you, but just wanted to share my experience.
