This could very well of been discussed before, but any information will be helpful. I have a 2010 A4 and has both auto lights and auto rain sensor; however, I noticed it doesn't have an auto dimming rearview mirror. Kind of annoying. Anyways, does anyone know if it is possible to swap the crappy standard one with a OEM dimming mirror?

 

There's a power button on my mirror I think. If you turn it on it will auto dim. Is there a button on your rear view mirror?
