Just a quick question! Is it possible to use my Direct TV card from our house unit in the unit in our motor coach? I'm tempted to try it this morning, but thought I'd ask. I turned the unit on and tried to raise the dish (not DDS), but it's not coming up, so it might just need the card to operate. I know I will need to re-program everything, but just trying to save a buck, or more like a hundred. Thanks
