I know I have mentioned this before but I just typed in my serial number and it said that I had the latest in radar performance. From what I read on this board, the latest software/hardware version is 3.826 and I have 3.819. I know I dont have the lastest hardware version and possibily software as well. But and here is my complaint - I wish when you type in your serial number the Valentine web site would report what THEIR latest software version is. I know what mine is, I dont know what theirs is. I guess I will just wait till a new version (1.9?) comes out. Drive saftely and happy motoring.
