i have ahd this rd for 2 days. I dont know if its a problem or not, but i drove down a road once today, and i locked out all the k band on the road. There are like 20 auto doors..( No Joke!) And about 2 hrs later i drive back up the road and i get hit by 2 k band. no cops ( cops in that area dont use k they use Ka only) could i have just missed a spot on my way down or did it loose some of it memory?
