I dicked with this more this morning. I just can't get it to work. The RF headphones only play for the DVD sound. I can get the AUX input sound over the speakers in the truck and through the wired headphone jacks in the RSE but not through the IR headphones. Only thing I haven't tried is the third row screen and IR headphones.Odd, we've used an Xbox1 connected and the IR headphones worked. Did you try flipping the A/B switch on the headphones?
I use a pure sine wave 300w max inverter plugged into the 12v outlet by the RCA ports and an RCA model DHCOMF HDMI to RCA adapter plugged into the aux ports. It doesn't need auxiliary power. Kids use the 2 USB ports on the inverter to charge their phones.
