    That's the idea of making sure it doesn't get activated by the interior light or when you are in reverse gear. Any other time, if it dims it is for a reason.

    I am interested in this retro fit and the parts used. The sources for pins 1, 2 and 3 would be good to see documented.

    i take your point GSB, having looked at the newer dimming mirrors they have a switch on them just makes me wonder why they have them unless they dont have them wired to the interior light. i just dont want to come unstuck if it does dim for no reason, even though it shouldnt do. I think what i will do is fit it without switch and see how i go.

    My Mercedes had one and my BMW has one, neither have a switch. I think you'll be fine without, so long as you have the interior light and reverse light feeds connected.

    Keep us informed of how it goes, I really miss this on my S4 and would love to do the retro fit. A shame it's not a plug and play retro fit like it was on my Merc.

    Good luck.
