Not sure if this has been addressed. I have the 6000 (will have a 510 installed Monday, and will be replacing the 6000 with a 921), and plan to get Superdish when it's available. Question is will the free install include a legacy adapter for my 6000 alongs with the DP34, or will I have to get one in advance to keep the 6000 running until the 921 shows?
