Windshield and Radar block...

[B-Line]

Can anyone tell me if the E70 X5's have that annoying windshield which prevents a Valentine 1 radar detector from working properly?

In both my current 750i, my gone but not forgotten E53 4.8is and if I remember correctly, even in my 2001 E53 4.4i.. The front windshield had some sort of film or treatment, that prevented my Valentine radars from indicating detection in front of the car..

Does this problem still exist in the current vehicles?

Thanks.
