Dual Headrest DVD Components
The Dual Headrest DVD system includes:
* Two video display screens
* DVD Control Module
* A Digital Versatile Disc (DVD) player built into each monitor - If equipped with Dual Player
* Two sets of wireless infrared headphones
* A remote control

Dual Headrest DVD Player
The DVD players are integrated the display screen. The DVD player can be controlled by both the buttons on the DVD player and by the buttons on the remote control. The DVD player power may be turned on when the ignition is in the run, accessory, or retained accessory power (RAP) power modes. DVDs are manufactured with different region codes based on the country in which they are sold. Therefore, the DVD player is only compatible with the region code where the vehicle is sold. The DVD region code is printed on the jacket of most DVDs. Home recorded CDs, CD-R or CD-RW formats, may not play in the DVD player.
Playing a Disc
To play a disc, gently insert the disc with the label side facing the back of the vehicle, into the loading slot. The DVD player will continue to load the disc and the player will automatically start if the vehicle ignition is in an enabled power mode. If a disc is already in the player, press the play/pause button on the face of the DVD player or on the remote control. Some DVDs will not allow the user to fast forward or skip the copyright or previews. Some DVDs will automatically begin to play after the previews have finished. If the DVD does not begin to play the main title, refer to the on-screen instructions, and press play on the DVD player buttons or on the remote control.
DVD Messages
The following errors may be displayed on the video screen monitor.
Disc Format Error
- This message will be displayed if a disc is inserted upside down, the disc is not able to be read, or if the disc format is not compatible with the DVD player.
Load / Eject Error
- This message will be displayed if the disc is not able to properly load or eject.
Disc Play Error
- This message will be displayed if the DVD player cannot play the disc. Severely damaged discs will cause this error.
Region Code Error
- This message will be displayed if the region code of the DVD media is not compatible with the DVD player.
No Disc
- This message will be displayed if the play button is pressed and there is no disc in the DVD player. If the disc is inserted wrong, the DVD player automatically ejects the disc and No Disc displays.
Parental Control
Part of the SETUP MENU lets users control the type of movie rating content (from G to Adult) that can be viewed and is only accessible when no disc is loaded. The parental control feature limits viewing to the selected preference. If a disc is inserted into the DVD compartment slot and it exceeds the Parental Setting, the following message appears on display: "The Parental Setting of this player prohibits play. Would you like to allow this disc to play?"
If yes if selected, the six digit password must be entered for the disc to play. If the wrong password is entered, the following message appears: " This movie will not play due to the Parental Setting of the player. To create a six digit password, use the numeric keypad on the remote control. Press the ENTER button to confirm." The default password is 136900.
Video Screen
The rear display screen shows video from either DVD player, or an AUX input device, such as a video game console or camera. Each video screen has a dedicated video signal circuit to the DVD control. If the vehicle is equipped with rear seat entertainment, there is no way to source the movie from the rear seat entertainment to the Dual Headrest DVD screens.
DVD Control Module
The two video screens are linked together by the DVD Control Module. This module allows screen 1 to source the media being played on screen 2. Video, audio, power, and remote signals are sent from the DVD Control Module, to each of the video screens. Video and audio signals are sent from the screen to the control module, and then to both screens.
Remote Control
To use the remote control, aim it at the infrared window above the video screen and press the desired remote control button. Direct sunlight or very bright light may affect the ability of the entertainment system to receive signals from the remote control. If the remote control does not seem to be working, the batteries may need to be replaced. Objects blocking the line of sight may affect the function of the remote control.
If the remote control is to be stored for a long period of time, remove the batteries and keep them in a cool, dry place. Do not store the remote control in heat or direct sunlight. This could damage the remote control. Keep the remote control stored in a cool, dry place.
Wireless Headphones
Wireless headphones allow for rear seat passengers to use the Dual Headrest DVD player without disturbing the listening of front seat passengers. The wireless headphones receive audio signals from the infrared (IR) transmitters on the overhead console. This transmission is line of sight only, so audio quality will be degraded if anything blocks the transmitter signal from reaching the headphones, or if the headphones are placed in the front of the vehicle. On some models, the infrared transmitter will have red LEDs illuminated when activated.
The wireless headphones include 2 channels. This allows rear seat passengers to utilize both screens individually without disturbing one another.
Each set of headphones has a rotary volume control. To adjust the volume, adjust this control. The headphones may 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 that are located near the video display screen.
AUX Inputs
The AUX input jacks are standard color-coded RCA-style jacks. Video is yellow, right audio is red, and left audio is white. The jacks are located on the front of the monitor. A number of devices may be plugged into the AUX jacks, including, but not limited to video game consoles, digital cameras, camcorders, or other devices. Audio only sources can be played through the AUX jacks from portable audio devices.
Audio Outputs
Audio from the DVD player or auxiliary inputs may be heard through the following possible sources:
* Wireless infrared headphones
* Vehicle speakers - via the FM transmitter (if equipped)
* Wired headphone jacks on each monitor
The Dual Headrest DVD system will always transmit the audio signal by infrared to the wireless headphones, if there is audio available. The Dual Headrest DVD system may be capable of outputting audio to the vehicle speakers via the FM transmitter. Once the correct FM frequency is selected as an audio source on the radio you may adjust the speaker volume on the radio to control the volume of the audio to the speakers. Only one audio source can be heard through the vehicle's speakers at a time. The audio source being used is specified by the A/V (audio/video) source selected on the driver side head restraint monitor.
The Dual Headrest DVD system is capable of outputting audio through the wired headphone jacks on the monitors.
Wired Headphone Jacks
Each headrest monitor is equipped with a 2.5 mm jack for wired headphones. To use the wired headphones, plug the headphones into the jacks. The headphones can be used to listen to any source the Dual Headrest DVD system can source.
