JJ, looks like you have the same model as I do. I just installed an in motion satellite dish. I paid extra to have the outside TV hooked into the system. My outside TV wasn't picking up the signal. After some investigation I found the cables they installed from the midship TV station were cut. I found the cut under the kitchen sink, under the rack that is made for the stove and sink cover plates.
I'll be bringing it back to the dealer once my trip is over.
