I have one on my TOYOTA CELICA in New jersey and a Cobra CB Radio with a K40 antenna monitor always on channel 19 were almost all the trucker tune . The brand of radar detector is FOX .visor clip mount . It is very important to me .I always travel at Route 95 highway .From my house Oxon hill Maryland going to Bethesda MD.takes less than an hour without traffic. Its like MANILA to Angeles distance . The state tropper we call them SMOKEY .OR GRASSHOPPER always hiding in the bush with radar detector. One time we were going to New Jersey on the highway i remember There one guy in a Mazda RX-7 . A BMW , Were driving over the speed limit and i see my radar detector beep and light . I slow down and after a few minutes a trooper pull down the guy with a mazda RX7 . I saw also the BMW has a radar detector also which light also. The CB radio is also important because trucker who approach a state tropper will warn other vehicle who monitor in channel 19. In VIRGINIA it is illegal to use radar detector. Just sharing my experience.
