the windscreen is definitely non UV-reflective. I had mine replaced the other week by Autoglass and the fitter brought the wrong screen even though I told them twice over the phone that its non-reflective. Apparently they get the vehicle info off the DVLA - maybe Autoglass cant read!
I think the reflective ones have a tint to them.
I made sure they used the right one because if my GPS unit on my PalmPilot.
BTW I also had a dent put into my drivers door at the same time my windscreen was replaced. Trouble is Autoglass deny all knowledge and I cant get the CCTV tape. So if you can, use anybody but Autoglass.
Cheers,
