There used to be an issue with the 211Z frimware when connected to a dome type antenna. Where you able to see the software go through the Step 1 of 5 to the point where a screen pops up and tells you to call Dish to activate the service? If so, that's really good news for the rest of us.
As to your KVH dome, if it is setup for DirecTV you will have to find a KVH tech with the required computer hardware and software to change the antenna over and get your software updated. This generally costs around $200 if you can find someone who still does it. They are out there, just sometimes hard to find.
