Greetings to all! I've just purchased a used 2008 Corvette Coupe that I "believe" has a radar detector/jammer. In the front grill there are 2 "scanners/receptors" and there is 1 in the back above the licence plate. In the car on the dash is a green light that stays on when the car is on. There is nothing else (visual or audio) inside the car. I can't seem to find any other indications on what brand this. I would like to find out so I can go to a reputable seller in order to see how this thing is suppose to work. I am located near Philly. Any help would be greatly appreciated!!
