I've got "semi-metallic" tint... it's kinda like mirror tint, and there's supposedly metal in the tint, however my radar detector works fine, even through the vinyl window banner I've got now. (I'm pretty sure the laser detection won't work through the vinyl though.)
Matt, I think your antenna's jacked because your installer cut the trace for it when he was trimming the vinyl or something... even with tint over the lines you should still get some radio, not just static on the AM band.
