IR Module
WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
Eight infrared light emitting diode (LED) transmitters are used to send audio signals to the wireless headphones that are included in the system. These LEDs are located on the driver's side Seatback display, and aimed to provide signal to any rear seating position. During operation, the LEDs may be visible through the lens on the driver's side display, but not on the passenger side. This is normal operation; the illuminated LEDs are located on the driver's side Seatback display only.
