Each screen houses an IR receiver. The IR receivers are connected to the rear seat entertainment module (RSE) (16/124) and are activated when the rear seat entertainment module (RSE) is supplied power. When a button is pressed on the remote control, it emits a signal with infrared light. The coding of this signal varies depending on which button was pressed. The IR signal is received by the IR receiver below the respective head restraint screen (16/81A, B) and is forwarded to the rear seat entertainment module (RSE) for processing.

The remote control can be used to switch between different audio and/or video inputs in the system:

The remote control is used for selection by aiming it at the screen that is to respond to the command. The command from the remote control is received by one (or both) of the IR receivers located below the screens (16/81A, B). The integrated infrared receiver is activated when the rear seat entertainment module (RSE) (16/124) is supplied power. The receiver forwards the command to the rear seat entertainment module (RSE). The rear seat entertainment module (RSE) will select AV or audio source for the screen in question. The remote control can then be aimed at the other screen to select a source for that screen.
