Got my first travel trailer. A 2016 Jayco 27BHS which came with a Furrion DV3200 entertainment center. Worked fine at my base camp. On my first camping trip, at the campground all hooked up with electricity and water, now it sits there lit up on an FM station and none of the buttons work. Can't even turn it off. Only the volume knob seems to work. Turn the volume and it takes 2 to 3 seconds to hear a beep and volume goes up one number, turn the knob and again 2 to 3 seconds for another volume number. Any suggestions?
