What does the age of the remote has to do with it? The software will allow you to program the dam remote. The history of the mx-850 is long, first released as the Orion, changed names to Aeros, then the mx-850. The Nxg nx-rm820 is the same as the current mx-850, it works with narrow band RF basestations.
If the model isn't in the software, you teach the commands, it doesn't take that long.
