JOE, if I may clarify your question. Are you asking if your "smart device"(which would have to have the consumer loader program on it), that would be used to run your trains, will be capable of doing the updating of your TIU, remote, WiFi unit, and also load engine sound files, wirelessly, instead of using a PC hardwired to the TIU like we presently do? If so, the answer would be no. You still need the PC. Maybe someday it will be possible and sure would simplify things.
