DVD PLAYER

The DVD player is designed to be compatible with Digital Video Discs (DVD) authorized for use in the United States and Canada. 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.

On power-up, the DVD player is in Auxiliary (AUX) mode. When a DVD begins playing, it switches to DVD mode. Pressing the PWR/AUX or SOURCE button returns the player to AUX mode. Pressing Play from AUX mode puts the player in DVD mode.

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 vehicle speakers. Or, a portable CD or digital media player can be connected to the audio inputs to use the vehicle speakers.

The DVD player sends the video signal to the roof console for video display. Video sound is output to the AVI module where it is sent to the radio for vehicle speaker sound and the roof console for headphone sound.

The DVD player can be controlled by the front panel controls or 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 and AVI module.

Power and grounds for the DVD player are the same as the Radio. Connections in the AVI module splice the DVD player power and ground into the radio power and ground. The DVD player provides power to the roof console through the wire harness and AVI module.

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 from the remote control are sent by the roof console IR transceiver to the DVD player through the wire harness and AVI module.

The video display screen activates when it is un-latched and pulled down. Pushing up and latching the video display screen turns the screen off, but leaves the audio headphones and remote control features on.

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

RADIO

The radio receives audio input from the entertainment system AVI module. Audio from the DVD player is selectable at the radio like other radio media (CD or Cassette Tape) by pressing the AUX button. The radio makes the video AUX mode available when IGN #2 and IGN #3 are high (battery voltage). In video AUX mode, the radio display shows AUX and fade, balance and tone control are available.

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 AVI module relay switches to connect the OnStar® audio to the radio audio inputs. In OnStar® AUX mode, the radio displays AUX 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.

AUDIO VIDEO INTERFACE (AVI) MODULE

The Audio Video Interface (AVI) module connects between the vehicle harness and the radio. The AVI module connects the entertainment system to the audio inputs of the radio and splices the entertainment system power and grounds into the radio power and ground. The AVI module also overrides the video sound input to the radio during an OnStar® call. For the vehicle speaker outputs, amp sense and park lamps input circuits, the AVI Module functions as a junction block, with no other connections to these circuits inside the module.

During DVD player operation, the DVD player audio enable circuit is low (grounded). The AVI module logic turns on the audio relay to connect the DVD audio outputs to the radio audio inputs, and causes IGN #2 and IGN #3 circuits to be high (battery voltage). When IGN #2 and IGN #3 are high, the radio mode switches to video AUX mode.

DVD player audio is interrupted when OnStar® is in use. During an OnStar® call, the OnStar® mute circuit is low and the AVI module logic turns off the audio relay. This disconnects the DVD player audio outputs and connects OnStar® audio outputs to the radio audio inputs. The AVI module turns Off IGN #2 and IGN #3 and the radio switches to OnStar® AUX mode.

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. The radio does not need to be On or in video AUX mode for the headphones to work.

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 and AVI module.
