Need some new/old RV gizmos identified.

[BZLuck]

I'm slowly going through and updating our new-to-us 2006 32' National RV Sea Breeze.

For some reason the previous/previous (original) owner removed the dash head unit and covered it up with a metal plate. Upon further inspection, I've found lots of coiled up cables underneath, including (yay!) a 16 pin stereo connection, and an antenna jack, so adding a new receiver should be a snap. (I hope)

However... There were 2 cables coiled up and zip-tied back there. I don't now what they go to. There is also a mystery "antenna" on the roof which *may* go to one of them. Any help to ID them will be appreciated.

Can't help on the DIN plugs, but the antenna looks like a satellite radio puck antenna.

For the record there is also a "King Quest" satellite TV dome on the roof. Maybe one DIN cable belongs to it, or whatever you would hook it up to?
