Circuit/System Description
The infrared remote signal is used to transmit signals from the rear seat entertainment (RSE) remote control via pulse width modulated (PWM) signals to the radio. When a key on the remote is pressed, the remote control sends an infrared message to the infrared receiver located in the DVD display. The infrared receiver converts these infrared signals into a frequency and sends the message to the radio to perform the appropriate function. Both seatback displays contain receivers for the infrared remote, which are connected to common (+) and (-) signal circuits to the radio.
