I was in Virginia last month and a couple of times troopers pulled up beside me in attempt to see if I had a RD. I have 5% tint on my windows and the RD unit is on my dash with velcro--I can't get it off---LOL. just as the trooper stated to pull in front of me I disconnected the cord. Each time the trooper was approaching he was shooting radar but I never hit my brakes or anything to let him know I had a RD.
I have a Beltronics.
