With a one-for-all brand remote (or most any remote made by UEI), you can start with your marantz code and find all other commands by trial and error. There are usually only 256 possible codes for all commands. So once you get the remote and find the partially working marantz code, try all 256 "magic" codes to find all the other missing functions. Post back if you find such a remote and we can tell you if it will work and give more detailed steps.
