I have a V1 with 3.824 that is a couple months old. Yesterday it junked out a real signal from a MI State Trooper. He turned the corner about 1/2 mile ahead and came towards me. The signal got almost full strength and then it "J"d out. I quicked powered off and on and it went back to full signal for about 1 - 2 seconds and "J"d out again as he passed me by. I thought that fixed this problem!
