2 things. Valentine will update any of his V1's for free, so ones that are on ebay may have old software, but they are updateable. You can buy directly from them online. That's where I got mine. Quick shipping and a great unit. Saved me just yesterday, a red camaro got nailed and i was passing them at 90 mph, it went off, i slowed down and they came flying past me. Yeah, she got pulled over. My associate was about 25 miles behind me, the camaro was getting put on a flat bed, i'm sure for wreckless driving. Buy the V1!!!!
Here's some irony, I was in WV on I-81!!!!
