I bought it 2nd-hand off
eBay in Jan 2014, so I guess that marks it as pretty early. It has the USB socket. I guess I'll find out. If not, too bad - not worth paying to get it update, better as you say to get a new turbo. I think in that case I'll just be happy running BKool for a while, and get a newer one eventually.
I do like the video playback feature of BKool, which makes their software worth it to me. I like exploring new routes, and its not the same if its just computer-generated imagery loosely based on the map.
