Hey everyone. I'm new to this forum. I'll cut to the chase. My father "left" us some years back. I was recently going through his old things and found a V1. I remember him using it in the car when I was younger. He always had the very best of everything, so I know that V1 was, and still is, the best. All that I could find was the V1 unit. I have already ordered power cables, cigg lighter power plug, and windshield mount. I also looked into the upgrade at v1.com, it says that the upgrade isn't necessary if I'm only interested in upgrading radar protection. I have no POP, but because I live in a small town in Indiana and only travel to Chicago once in a while, I don't see this as a problem. What I'm asking for is your opinion on whether or not I should purchase the upgrade for $229 plus shipping? Please remember I'm a 21 year old on a restricted budget. Thank you so much for all of your help.
