I wanna buy one Radar Detector, Escort Passport 9500i OR Beltronics STi Driver , As far as I knew, there're the best models in the market, but my question .
1. Both of these models can detect speed camera?
2. Escort Passport 9500i uses GPS technology, If we go somewhere that there's no GSP signal about radars, does it detect radars with it's manual antenna without using GPS?
