OK, know this is dumb but when we got our Landmark we didn't realize that they come with no radio - zero, zilch, nada. Thought the radio was part of the DVD system -wrong. So the question, has anyone added a radio to a LandMark 365 system, or another product? Would like to get surround set up but given what we understand for the roof/ceiling, I don't believe that snaking wires is possible - any experience with that also. Thanks in advance.
