I've wanted a V1 for quite sometime but could never really justify the price. Anyway, I was in a pawn shop the other day and seen a V1 in the display case. I asked the guy behind the counter how much he wanted for it and he told me $150. Sounded like a good price to me, but, it is a pawn shop so you always gotta haggle a little with em'. I asked him if he'd take $125 for it out the door and he agreed so I bought it. I think this is one of the first times I have ever gotten that kind of deal out of a pawn shop. (Perhaps he didn't know what he had?) Anyway, I took it home and ran the serial # on Valentine's website and was told that I "had their best." I'm assuming this is the most current version of the detector. Anyway, my question is this: With detectors I have had in the past, they usually will shut themselves off immediately or after a certain period of time after the car has been shut off. The V1 doesn't seem to do this. Is it ok to leave the unit on in my car when I am not in it? I just have it plugged in via the 12v outlet in my 06 F-150. Thanks everyone! Already loving the V1!
