Hello fellow RD users, I am currently in the process of purchasing my first radar detector which will be the Valentine One. I just have a few questions about purchasing it. 1. When purchased directly from the site, do i get the latest model and the latest version? Or do I have to buy the newest upgrade? 2. Whats the best upgrade to get for the V1? 3. How can i tell from the oldest and latest model of the Valentine One (I don't want to get stuck with an old version of the Valentine One). Thanks and hope to hear from you guys!
