There is an infrared receiver (IR receiver) in each screen. The IR receivers are directly connected to the Rear seat entertainment module (RSE) (16/109) and are activated when the Rear seat entertainment module (RSE) is voltage fed. When a button is pressed on the remote control a signal is sent out with infrared light (IR). This signal has a different coding depending on the button pressed. The IR signal is received by the IR receiver under the screen (16/81A, B) on each head restraint 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:

  • DVD player, audio/video
  • AV-panel, audio or audio/video
  • Audio/video from a TV receiver (if installed) to one or both screens.

Selection is performed by aiming the remote control at the screen where the command is to be executed.

Depending on which of the two screens that received the command, the Rear seat entertainment module (RSE) will select AV- or audio source for that screen. Then the remote control can be aimed at the other screen to select source for that screen.
