Circuit/System Description
The second row overhead display is located in the headliner. The display screen shows video from the media disc player, or an AUX input device. When equipped with RPO DNU, a 3rd row overhead display is added to the system.
The overhead displays receive power and ground from the vehicle harness. A discrete control circuit from the media disc player is used to control the power state of the displays. The displays receive all other video, audio, and control information via the LVDS cable.
The 2nd row display contains the infrared transmitters for the wireless headphones. During operation, the infrared transmitters may be visible as illuminated LEDs. The LEDs are not on visible on the 3rd row display. Both displays contain an infrared receiver for the remote control.
A power button on the headphone is used to turn the headphone on. A red LED illuminates when the headphone is turned ON. The headphones automatically turn OFF if they lose the infrared signal from the system for approximately 4 minutes in order to preserve their battery power. The signal may be lost if the system is turned off or if the headphones are out of range of the infrared signal transmitters.
Each set of headphones has a rotary volume control on one of the earpieces. to adjust the volume, adjust this control.
Audio to the wireless headphones is provided over 2 channels. Audio for channel 1 is from the source of the 2nd row display, audio for channel 2 is from the 3rd row display. This allows rear seat passengers to utilize the screens individually without disturbing one another. Pressing the button in the center of the headphone volume will switch the headphone between channels.
