Installation-requires major rewiring unless your boat was originally designed for this. It does not work on any dish equipment that you can currently get from Dish. If someone has an old receiver, definitely prior to a vip 211 k, it might work. I would save yourself the time(in my case about 30 hours) and the money(installer charged about $600 without the cost of the MIM) for something that Intellian even says doesn't work well.
