Thanks Bob I received the manuals by contacting your support group. Was interesting to hear our dealer tell us that only the radio played thru the 5 speakers in the ceiling (including sub) and that the TV would not really play 5.1 surround with those same speakers, then finding information online that Palomino has historically hooked up the RCA cables incorrectly. I looked at ours and they had connected the out of the iRV to the in on the TV instead of the out on the TV to the in on the iRV.
I have it back at the dealership now getting some issues fixed and plan to connect the optical from the TV to the iRV, just wish I didn't have to remove the unit to make that connection.
first trip in 2 weeks so hope we don't find to many more factory issues.
