2004 Mountaineer Premier
Here is the story of my OEM DVD adventures for my 2004 Mountaineer Premier. It has the built in overhead DVD with the sunroof. This is different than the Mountaineers without the sunroof that uses a similar but different setup.

I bought the car used and the in dash 6-disc CD-Player didn’t work. At the time I didn’t care since the previous car had a nice Pioneer HU that I planned on using anyway. Well that backfired because I soon figured out the DVD Player is tied into the OEM HU. This is when I realized I was in trouble. I really wanted my Pioneer HU to work with the OEM DVD setup. I did a ton of research and this is what I ended up doing.

The OEM DVD will ONLY work with the stock HU. The DVD controlling interface is proprietary and no-one makes any boxes or controllers that will tie into it. To make a long story short I ended up using my Pioneer HU up front to drive the audio. I hid the original OEM HU under a seat in the back and use that to fool the DVD player into working. I just left the OEM HU in DVD mode and pipe the audio from the DVD player through the Pioneer HU aux input. This allows me to keep the OEM DVD and have it operate with the sound through the Pioneer HU.

To pull this off I used:
- Standard Dash Kit (http://www.installer.com/item/display_item.php?it=70-5521)
- Factory Harness (http://www.installer.com/item/display_item.php?it=71-5520-1)
- RCA Ends (http://www.radioshack.com/product/index.jsp?productId=2103848)
- IP Bus RCA Adapter (http://www.installer.com/item/display_item.php?it=pxrpio)

I hid the OEM HU under the middle seat of the middle row. The seat flips up to expose a plastic cubby. It is removable which yields far more room. I took this out and dropped the radio in. I used the Factory Harness to plug into the OEM HU. I used a random cable that’s similar to a CAT5 cable from Lowes to connect to it. The install needs 6 wires, so any wire that contains 6 individual wires and has stranded wires should work well. I ran this from the dash, down the drivers’ side, and under the middle seats to the OEM HU. This allows me to send the 12v constant, 12V remote, and ground to the OEM HU from the dash. It also allows me to receive the 3 wires of DVD controls from the OEM HU in the dash.

To get the OEM HU to run all I needed to connect was the 12v constant, 12V remote, and ground. These wires are all in the 24 pin harness (red, yellow, and black). This allows the OEM HU to power up. Then the 16 pin harness has 3 wires just for the DVD player control interface. Of the 16 pins only 7 are used. On the one side of the harness are the 3 wires for the DVD control. These need to be connected between the OEM DVD and OEM HU. For reference the other 4 wires are on the opposite side of the harness and they are the inputs for the DVD audio. We don’t need those here.

The 16 pin harness in the dash has 4 wires containing the DVD sound (left and right + and -). The red and orange wires are the positives from what I understand. These 4 wires are all on one side of the harness. I connected the RCA ends onto these and connected these to the IP Bus RCA Adapter on the Pioneer HU. This pipes in the DVD audio under AUX2 on the Pioneer HU.

On the Pioneer P4000UB it allows inputs to be renamed. I set AUX2 to say “DVD PLAYER”. This also leaves a auxiliary headphone jack on the front of the Pioneer HU as AUX1 free. This is what I used for my portable XM Player. I set AUX1 to say "XM RADIO". I thought that was a nice touch.

While I was in there I also added a resister in the sub remote wire to eliminate the sub turn on thump and a PAC SWI-PS that ties the Pioneer HU into the steering wheel controls.

I have seen this issue solved the exact same way. I believe you have a year (2004) that has no solution from the aftermarket and the only resolution is exactly what you did. I know of a couple of trucks that did the exact same thing. Good work around.

I do have a bit of concern though with your choice of cabling. I'm not sure CATV cable is heavy enough to supply the power and ground for your OE radio safely.

I would have to agree with Cobraguy -- CAT5 cable is designed to max out at around 800mA - 1A, since transmissions via Ethernet don't need much current.

Powering your HU with it is just asking for trouble -- I'd pull some 16ga or something along those lines for the power.
 






Similar to CAT5, as in the construction of the cable. I didn't actually use CAT5. The internal wires were bigger and stranded as well.
 






Just an FYI, I bought an extra console off Ebay to have a spare. It is the entire plastic console including the DVD and screen. I no longer need it and will sacrifice it for $100 plus shipping.
