DVD Player

On this vehicle the DVD player is integral to the radio, which uses the same slot loading single disc player for audio CDs and MP3 CDs. The DVD player is designed to be compatible with digital video discs (DVD) authorized for use in the United States and Canada (Region Code 1). Regular audio compact discs (CD) can also be played by the DVD Player. Home-recorded CDs (CD-R) or home-recorded DVDs may not play in this player.

Auxiliary input jacks are provided to connect video and audio from other devices. For example, video games or cameras can be connected to use the video display and headphone audio. Or, a portable CD or digital media player can be connected to the audio inputs to use the wireless headphones.

The DVD player sends the video signal to the roof console for video display. Video sound is output to the vehicle speakers and the roof console for headphone sound.

The DVD player can be controlled by the remote control. Remote control commands are transmitted by infrared (IR) signal to the roof console IR transceiver. The roof console IR transceiver sends the IR signal to the DVD player through the wire harness.

Power and grounds for the roof mounted DVD screen come from the Radio.

Roof Console

The roof console houses the video display screen, infrared (IR) transceiver and video/audio electronics. Video signals from the DVD player are processed and displayed on the video display screen. Audio from the DVD player is converted to infrared (IR) output signal to the headphones. Only DVD player audio is available through the IR headphones.

IR signals form the remote control are sent by the roof console IR transceiver to the DVD player through the wire harness.

The video display screen activates when either a DVD is inserted or selected as the source from the radio head/DVD player; or when an auxiliary device is connected.

Power and ground to the roof console is provided by the DVD player through the wire harness.

AUX Devices

The roof console has RCA-style jacks for connecting auxiliary devices. The jacks are color coded. The yellow jack is for video signals, and the red and white connectors are for right and left audio, respectively. The radio/DVD player utilizes a microswitch in the red jack to detect the connection of an auxiliary device, which will cause the radio to turn on the display screen. In order for an auxiliary device to work, an audio cable must be connected to the red jack (either the red cable or mono sound cable). If a DVD is inserted into the player, AUX devices will not work.

The audio from an auxiliary device will only be played over the wireless headphones, not the vehicle speakers.

OnStar®

If the vehicle is also equipped with OnStar®, DVD audio will be interrupted during an OnStar® call. During an OnStar® call, the mute line is low, ground, and the radio switches to play the OnStar® audio to the vehicle speakers. In OnStar® AUX mode, the radio displays PHONE and the fade is fixed at full-front, balance control is fixed at center, and the tone control is fixed at a pre-set equalization. Volume level can be adjusted as needed or desired.

Headphones

The wireless headphones receive audio from infrared (IR) signals sent by the roof console IR transceiver. The headphones only receive audio from the DVD player or an auxiliary device.

Strong sunlight may interfere with the IR signal and headphone sound operation.

Remote Control

The remote control sends infrared (IR) signals to the roof console IR transceiver. These command signals are converted and sent to the DVD player through the wire harness.

Parental Control

Parental control will pause DVD playback, mute the audio, and display "Parental Control On" with an otherwise blank display screen when turned on. The driver may press the RSE button on the radio/DVD player to initiate or cancel parental control.
