Here is a tidbit for you. No where is it documented what the connections on the wall by the T.V. mounting area actually go to.
The top wall plate has 3 RCA Jacks which are for OUTPUT, and they go to the Furion DV 7200. The red and white are for audio, and the yellow is for video. However, the Furion (as it is cabled) does nothing with video. What you CAN do is hook up the audio output from your T.V., a DVD player or maybe a Blueray player; and run that through the Furion. Use the AUX feature on the Furrion to play the sound.
I thought that would be great for a "surround sound" when watching basketball games on T.V.! I ran into two caveats though. 1). If I connect the cables to my T.V., I MUST also turn the Furion on to listen to the audio. (Other T.V.s may be different). 2). The Furion system is MONO. It's not even a stereo. The more I played around with it, the more I think the whole Furion system is junk.
The cable wall plate has a cable/digital antenna coax connector, and a satellite T.V. coax connector. There is also a "booster" button for the digital T.V. antenna. Press the button and a green LED lights up. Turn it ON for antenna. Turn it OFF for cable T.V.. Also, the "booster" button is powered by the 12V system. Make sure it is turned OFF when storing the trailer, as it is a battery drain.
