i took my dads car the other day and mounted my v995 in it. i was doing some errands around town for him and i realized that the detector was really quiet. i saw quite a bit of x band but since i have it on city lox i didnt get any audio alerts for those.
all the usual k band sites seemed to go undetected unless at a very close range. i even saw a cop pull out of a neighborhood and come toward me on the other side of the road with his k band on and i got about a 3 or 4 alert where i should have been getting full like i do in my car.
i also got farther rear detection on all the k falses than i did front (i had the windows and sunroof open so i'd assume the windows wernt killing detection from the rear).
i know he has some special coating that came on his windshield when he bought the car so i'm assuming that this is whats causing it. just found it to be really weird...
oh, and i put it back in my car and k band is great, so i know its not falling out of tune.
