WARNING: This page is about a different car, the 2011 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.
RSE Power
The rear seat entertainment (RSE) uses a switched battery voltage feed circuit for power moding. The radio outputs power to this circuit via the entertainment remote enable signal circuit.
RSE Grounds
The vehicle harness provides a ground for the RSE circuits.
RSE Data Link Communication
The RSE does not communicate with serial data.
RSE Outputs
At minimum volume, the plus (+) and minus (-) audio signals are approximately half battery voltage, measured to vehicle ground. These audio signals are sent from the radio to the Infrared Module, most systems have a common minus (-) signal.
