They will change it out now if you want to pay for a service call. Or change out if they have to service your equipment. I called a few weeks back and the CSR tried to have a 512 shipped to me but the computer would not let them. Then they rolled a truck out , but did not bother to tell me their was going to be a $95 truck fee. The techs did not say anything when they swapped my 501 owned for a 512. Upon getting my next bill and seeing the $95 fee for something dish is forcing us to swap out , Dish csr's and I had some real intense negotiations and being about 5 secs from leaving dish I no longer owed them $95. So double check everything you do with dish.
