Overhead Console

The overhead console houses the digital versatile disc (DVD) player, controls for the rear seat audio (RSA), rear seat climate control, the flip-down display screen, auxiliary (AUX) input jacks, infrared (IR) transmitter for the optional wireless headphones, IR receiver for the wireless remote, and two 2.5 mm wired headphone jacks.

Power is supplied from the RADIO AMP fuse in the fuse block - right instrument panel (I/P). The overhead console is grounded through G201. The overhead console is enabled/dissembled by class 2 messages from the body control module (BCM). The BCM also allows for retained accessory power, which allows the radio to operate for up to 10 minutes after the ignition is turned off. The overhead console can only be deactivated by one of the following:

  1. Front door is opened.
  2. The 10 minute timer has elapsed.
  3. Loss of state of health message from the BCM.

DVD Player

The DVD played is a single slot loading mechanism that will also play standard audio CDs in addition to DVD movies. Home-recorded CDs (CD-R) or home-recorded DVDs may not play properly in the player. The player can be turned on and used anytime the ignition is on, or when retained accessory power (RAP) is enabled. The DVD player can be controlled either through the controls on the overhead console, the wireless infrared (IR) remote, or the radio head if the DVD is selected as the source. If the rear seat audio (RSA) is in use, the DVD player cannot be controlled by the buttons on the overhead console.

To use the DVD player, press the DVD power button, and pull the screen down. Insert a DVD (or audio CD) into the empty played slot. If a CD is inserted, it will automatically begin playing. If a DVD movie in inserted, it may begin to play, or the user may have to select an option from an on screen menu to begin playback. While watching a movie or listening to an audio CD, the user may use the controls on the DVD player or remote to perform the following operations (not all functions are covered in the following table):

Display Screen

The display screen shows video from either DVD movies, or an AUX input device, such as a video game console or camera. If an audio CD is played in the player, the screen may display artist/title/album information if available. The display screen will turn on when pulled down, and automatically turn off when pushed up and closed.

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 just forward of the screen. 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.

To use the AUX input, turn the power on to the overhead console, and push the AUX button. The display should show "AUX".

Parental Control

The overhead console is equipped with a parental control button. It is located forward of the AUX input jacks. When pressed it will stop playback of any source currently playing through the overhead console. A DVD or audio CD is paused and the screen is blanked. When pressed again to cancel parental control, operation returns to normal.

Rear Seat Audio (RSA)

Passengers riding in the rear seating rows of the vehicle may utilize the rear seat audio (RSA) system to listen to an audio source that is different from what is being listened to in the front seat. To use the RSA system, press the RSA power button, located on the overhead console. Users can change the RSA source to either the radio or the in-dash CD/MP3 player by using the SRCE (source) button. If the front seat passengers are listening to the same source, only front seat passengers will have the ability to control or change radio tuning or CD track and/or disc selections.

If RSA source is radio, users may perform the following operations:

Wireless Headphones

Wireless headphones are optional and allow for rear seat passengers to use the rear seat entertainment (RSE) or rear seat audio (RSA) functions without disturbing the listening of front seat passengers. The wireless headphones receive audio signals from the infrared (IR) transmitter 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.

The wireless headphones include 2 channels. This allows rear seat passengers to utilize both RSE and RSA functions without disturbing one another. The toggle switch on the right side headphone earpiece switches between channel one and channel 2. RSE is broadcast on channel one, and RSA on channel 2.

To use wireless headphones, turn them on using the power button on the left side headphone earpiece. Adjust volume using the rotary dial on the right side headphone earpiece.

Wired Headphone Jacks

The overhead console is equipped with two 2.5 mm jacks for wired headphones. The headphones can be used to listen to either the RSE or RSA functions. If both RSE and RSA are used at the same time, the wired headphones receive only RSA audio.

To use the wired headphones, plug the headphones into the jacks. Adjust the volume by pressing the headphone button on the left or right side of the DVD player face, and then using the FWD or REV buttons to adjust the volume up or down. Visual indicators on the DVD player display will indicate volume level. The left headphone button selects the left headphone jack for adjustment, and the right headphone button selects the right headphone for volume adjustment.
