WARNING: This page is about a different car, the 2009 GMC Envoy and 2009 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
The infrared transmitter is located at the bottom of the motor. When listening to the headphones, the infrared transmitter sends an infrared signal to the headphones. The audio that is sent from the DVD player to the radio is a varying AC voltage. The audio from the radio when tuned to XM™ can be over the audio from the DVD or CD when using the wired headphones plugged into the rear seat audio (RSA). This is considered normal operation.
