Been using a radar detector for a few years now (will not get into why, errrr, don't ask) with awesomely excellent results. Mounted in the rearview mirror mount (post for the install somewhere here in forum) so no-one will harass me about attaching anything on the windshield (some locals have ordinances about attaching suction cup accessories). Fear not, the detector will work as designed (if you get one that works right).
