Thank you all for sharing your infos and experiences. My X is an 03 model with no rain sensors it only has the simple anti glare and probably a temperature sensor on the rearview mirror assembly and has no connections (electronically) to the windshield. I then conclude that it will be the cheapest from the above mentioned pricelist.

I wanted to ask - are you sure the windshield comes with the rearview mirror assembly? But you seem to be sure that it does. Im just doubting because the rearview mirror assembly looks expensive to be just a part of the windshield package. Am I making sense?
