Also since you have experience with it, is it necessary to update the cable firmware to run the new software? OR can you get away with not updating the cable but just getting the software? Because if so, I'd want to just do a fresh download and call it something different, like UpRev New or something like that, so it doesn't overwrite my old software. That way I can still revert to the old software/tunes if I don't like the new version. Would this be possible?
