My hats off to you guys. I don't know how you tolerate the incessant chirping of these devices. As I stated in a previous thread I bought the Uniden R3 and programmed it according to the YouTuber Vortex Radar and the thing chirped all the time.....I sent the it back post haste. I have never been pulled over by law enforcement while driving my Porsches since I do all my spirited driving on the back roads of Texas, and strictly obey the speed limits on the public roads.
