Adam, I don't remember EasyC being available before about 2006-2007. I would guess that it would work on the older controllers (other than pre-2004), seeing as they're the same, other than memory capacity.

You bring up a good point about the radio modems, however, I seem to remember that the 2007-2008 model will work with the 2006 system. I may remember wrongly, though. Trying to remember just what changed other than the size and shape...
