Hello, we have a AXXERA AV615BH Radio/DVD player in our 2017 Four Winds Thor RV, Class C. We finally figured out how to use the radio but the DVD player doesn't play through our TV. It plays a movie on the dash screen but not the television. Can anyone give me instructions on how to get our player to connect with the TV? Thanks. I have reached out to the salesperson at Camping World, but so far, no response.
