Retro-fit auto dimming rear view mirror & rain sensor

To start with I think you will require a new windscreen as I believe the are different if the car is specced with auto lights/rainsensor. The sensor is part of the rear veiw mirror housing.
 
I have auto dimming rear view but not the rain sensors - can that be done easily?
 
No idea about the wiper thing, but you can get an auto-dimming mirror on Ebay, that is a piece of cake to fit. It's not a junk item either. It's made by the same component manufacturer who supplies the car makers. I bought mine about a month ago, it arrived the next day, and I fitted it myself in an hour.

It also works a treat. Details were posted in an earlier link.
