I have two rigs in my home that each use an MX 810, from back in that short period when URC was marketing it as a sort of a prosumer product. Having fought all the battles with the admittedly clunky "Wizard" Software, they're both beautifully programmed to do exactly what I want, but after several years of hard use, I'm worried about eventually having to replace them.

My question, does anyone know if the 810i is compatible with the older 810 software? Clearly I'd rather just buy one of the 810i handsets and load it with my existing programming than move to a completely different system or have to try to scrounge for a back-door copy of software specifically for the "i" model.
