RE: Windshield tinting composition
I don't know if there's metal in it or not, but I have a little electronic sensor behind it for bridge tolls and it reads through it just fine.
That said, for a radar detector it doesn't have to be metal; anything that blocks line-of-sight between the radar detector and the source will reduce the effective warning distance of the detector, be it trees, hills or little opaque shading dots on the windshield. (I've seen some people mount them low, right at the dash, behind the wiper mechanism...not the best spot!)
FWIW, I usually mount my radar detector directly to the left of the shaded-dot area as high as possible; so long as you're not in an area where it's illegal to have them I don't think the few inches one way or the other will do anything re: reception/warning distance.
Take care and enjoy the ride,
