Polarised windscreen
(think that's what it's called)

"Comfort Climate" windscreen - the posh option. Polarising is what it does to the suns rays. You should know that you have the Build Data!
It might be interesting to know what percentage of mirror failures with this screen are, as opposed to the conventional tinted Green stripe screen? Q - AlexK!
