Torque 325 TV and entertainment system

Recently purchased a 2016 Torque 325SS. This unit comes with just one TV mounted over the door. Question, has anyone tried to take that TV down? I have tried to figure it out and haven't had any luck. Would like to get to the back side of TV to plug in surround system.
Question 2; I have the BOSS audio system and have not been able to play a DVD. It shows on TV, so TV is receiving signal, but always comes up with error message. Has anyone had this problem? I have contacted BOSS on their website an haven't received any response from them. Any help on these topics would be appreciated.

If you are getting the error message then you have probably hit the reset button on the main unit. My Boss dvd player in my new 2016 321 Torque was giving me the same error message. It wouldn't play any dvd's or music cd's. My dealer replaced it under warranty and the new one works perfectly.
