New 2009 Super Nova Questions

[PieEye]

Hey Folks - New 2009 6400 owner here and I have a few questions that I hope you can help with.

1) whats the trick to get sound out of the bedroom tv and cabover tv? I have the av selector switch and I can get the dvd player to play on all the tv's, but sound only comes from the main cabin souround system. nothing from either of the other tvs.

2) I've got a prodigy brake controller. Anyone know if Internatinal or prodigy has a plug in harness like they do for most pickups?

Thanks in advance.
