The rear seat entertainment (RSE) system consists of two, 2-channel wireless headphones that are dedicated to the system. Channel 1 is dedicated to the video screen, while 2 is dedicated to rear seat audio (RSA) selections. The infrared module receives voltage from the rear audio/HVAC module when the RSA in ON. For DVD audio playback, the infrared module receives audio inputs directly from the radio. For all other audio sources, the radio audio signals are sent to the rear audio/HVAC module, which then provides those audio inputs to the infrared module to be broadcast to the headphones.
