WARNING: This page is about a different car, the 2012 GMC Terrain and 2012 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

The driver seatback DVD display contains the infrared transmitter for the wireless headphones. The audio that is sent over the DVD audio signal circuits is a varying AC voltage. The transmitter processes the signal and transmits the audio signals to the headphones. If the display is in the closed position, the infrared signals will not be available for the operation of the wireless headphones and the remote control.
