Actually, I think that they're wrong about the RM-X117 being a high-band remote. In any case, it works with the SWI-X, which is only supposed to work with signals in the 38-40 kHz range. Since the SWI-X recognizes both the Sony and Rio remotes, I was hoping that the empeg unit would be able to recognize the signals from the Sony remote.

The idea is that I want the SWI-X to only emulate the Sony remote, and have the empeg interpret some of those signals differently than the Sony head unit (when the empeg is active). So e.g. volume +/- would control the head unit volume, but track +/- would control the empeg.

Since the SWI-X can control both units, my hope was that the empeg could just understand the Sony signals. That's why I was asking whether the Button Codes Display was absolutely authoritative, or whether it might be missing something.
