sup all i recently purchased a V1 (its that latest one i checked) and so far its disappointing because i passed by cops with out any alerts. i tried many ways to test it. i reprogrammed mines to were its on factory setting and tried turning off the X-band and boosting the Ka band. "A" "l", and "L" settings. i live in socal and even with "A" mode on i pass by cops with no alerts. i did some research and messed around with the setting and still no alerts. i know that sometimes cops have the radar turned off but, come on! today i passed my 3 cops on the freeway and 2 cops in town, no alert. i'm thinking its a defective unit. any inputs?
