Yes I did it dispite V1's "not a good idea" I put 2 radar detecors in my car. My old Bel 955STI and the V1. The 955STI didn't go off once and the V1 went off as usuall.
Can someone verify that both detectors will "chat with each other" like V1 claims? Its kinda cool to have both detectors in the car (V1 high ) of course.
