Ok, today's my first time turning the X-band detection off. On my way back from work, the V1 went off on a Ka alert and started to increase up to strength level 3-4. It kept beeping for like 10 seconds (at level 4) then silenced. Since I was on the highway and there's no building or store on the sides (I believe Ka band is not used in automatic doors anyway), I just assumed it was a Cobra detector ahead of me or something. But then at another section of the highway I ran into the same freaken problem!!! I can't blame it on the poor Cobra all the time you know. So, I wonder if it's a false that some of V1 owners might occassionally get? I never had this experience on "Ka" before I turned the X-band off. I'll see if I ever run into similiar situation again.....which I hope not.
