Rear View Mirror Replacement
I just purchased a 2006 S40. I love the car, but really miss having an auto-dimming rear-view mirror. The car I purchased has the manual unpowered variety. I found a Compass-Auto Dim mirror on-Bay from a 2006 S40. My question is what would installation entail? I have installed many after-market mirrors on other vehicles before, so my question is more of a technical one. Does anyone know if the car has a standard harness for these types of mirrors? Is there a software upgrade required for the car? Any help would be greatly appreciated.
