OEM Headrest Monitor Help

[blorax]

I purchased an OEM headrest monitor set for an X3 off ebay. I'm trying to retrofit them into an E46, so I don't want the OEM DVD player.

The problem is that I don't have the pinouts identified for the 9 pin mini-din that comes off the monitors. Can anyone help me with this information?

Alternately, I'm also wondering if I can get a part number for the AV Interface that these hook directly to (unless they hook straight into the DVD). I'm assuming the interface is just a box that provides the RCA hookups, power, IR on the other side. Unfortunately, I don't have a system or wiring diagrams to see how these monitors are supposed to be integrated.

I would appreciate any information.

P.S. I'm so glad you X5 guys are here to drive the navigation hacking effort. There's not enough interest in that for the E46 (because not enough people have OEM navigation, I assume). You've been an awesome resource for me. Thanks!
