you need the hex-can-usb interface, that works with almost everything.
Still doesnt get you a licence from rosstech since its not coming from them, but may still unlock the full program (in a kind of illegal sort of way lol) - the one I got from china does. Mine was fatally wounded by the rosstech 704 upgrade, but may be fixable / half fixed. I only paid £19 for mine but it only worked with versions 409 and 607, though that was more than enough.
fleabay is full of replicas now, just buy the cheapest hex/can/usb one you can find, and get the freeware version of the program it needs. rosstech no longer give out ver 409 (maybe not even 607) due to the issues with copied cables (which arent illegal - not copyrighted or patented, existing technology and all that) but their software can only be unlocked by a "genuine" cable......enter the chinese
And you can get the software from some other sources, some come from fleabay with a disc.
