In my conversation with Madrigal Tech support about the serial number. I asked about additonal codes.

Dave, tech support person, informed that in the next couple of weeks they will be sending CDs with more codes to the dealers. You will have to bring your remote into the dealer and they would be able to update the remote. Since I live in Louisiana and I purchased my remote in Atlanta, I guess that option is out for me.

Currrently I have all my components on the remote without any problems with range, software, or anything else. I really like the remote.
