well im sellin one for 125. its a radar detector detector detector jammer. if it senses a cop scanning for detectors it tells you how far away it is and shuts itself off.
this thing is badass. i used to drive like 65 down eastwood and it would beep at me and the screen would light up and sure enough i would pass a cop.
lots of the new cop cars have radar in the grill that are always on so this thing lets you know if theres a cop anywhere around.
i dont need it anymore, im planning on gettin one that i can view through my tv when i pick up my new pt cruiser tomorrow.
its only a few monthes old. 125 $, still got instructions and power source. its got a digital compass too!.
