I took my HU out and looked at the back of it. The M46 has wires coming out of the 34,35,36,37,39, and 40 pins but when I wired pins 39 and 40 together in order to trick the HU into thinking there was a DVD player, it disabled the rear controls. The wires are a different color than the wiring diagrams I have seen. On that same connector, pins 21-28 don't have anything attached. Do you know where I could find a pin out for the '05.
Are you positive you had pins 39 and 40? I ask because you said the wire colors didn't match. You say it disabled the rear controls but did it at least activate the DVD on the HU? I think you may have things backwards. Pins 21-28 (plus a few more) are for the rear controls so them being empty does not make any sense.
Were the two wires you spliced violet and pink? If so you are on the wrong side of the harness. The diagram is looking at the face that plugs into the HU. It sounds like they didn't provide the wiring for the DVD...you can still do it though by going the way that Rs250R did and add the pins to the harness (refer to the link I posted above). You may need to order them or go beg your service department.
A alternate way may be to use the satelite prewire??? Now I don't know how this works, if you can get the audio to the rear controls while you listen to radio up front. Someone with satellite may be able to answer this. I think there is a small harness on the driver side under the dash that has the satellite prewire on it. I'm attaching the diagram but the more I look at the less I know

. I don't know how to handle the other data wires on there so the HU knows there is a signal coming from that way????
What you might be able to do is get a pin puller from like Radioshack and pull the wires from the Sat prewire and stick them in the DVD spots?
Sorry I can't help more than this....Guess Nissan found out that their hidden prewire for DVD had been found and they were loosing $1600
