I think I'm heading for a new windscreen this summer owing to the number of scratches that are appearing. I've seen plenty of threads and Internet posts on retrofitting a auto dim interior mirror and auto lights, but none of them have a DIY for the B7 and wondered if anyone on here has actually done it and was it problematic? I know a few people have got an auto dim mirror from Gentex but if I get a new windscreen, I can get an auto dim mirror for a few quid, thought I may as well go OEM in that case. Appears that HazeyDayz want to charge over £500!? Is it just a case of getting a windscreen (is the light sensor built into the screen?), mirror, new light switch and getting it coded?
