Does it. I have tried it with my 8103 and it works for it. I also have a 10x where I am now and am thinking about getting my copy at home shipped here. In order to go through all that trouble I would like to know will it work. I also don't have the adaptor for the 9303, just the basic version with the JR cable. I guess I can plug it into the DSC port, but other than that the 10x has no trainer cord.
