So far I have my EZPass transponder loose, sitting up on the dash on the rubber mat in front of the clock. (I have an SE, if that makes a difference). It registers fine from there. I've tried hand-holding it up "where it belongs" centered in the windshield, right up against the roof-line, and thus behind the black mesh. It also seems to register just fine from that position; the mesh doesn't interfere. I'm probably going to mount it there, though I'm a little concerned it will damage the pattern on the windshield if I ever need to remove the mounting strips. I've read that there are supposed to be underhood mounting options for EZ Pass (think about a classic Corvette convertible) but when I've called the folks at the PA Turnpike they've never known of such an option. So, I'm still pondering this. Tim
