Just installed a Pioneer AVICZ1 in an 05 Armada with a factory overhead screen and dvd player. Is there anyway to allow the overhead and rear controls to still work. Please help!!!!!!!!

Not that I know of. It like having satellite receiver and trying to use a cable box remote control. The only way the it might be possible is there is a device that some aftermarket HU can use to keep the steering wheel controls funtional. Don't know who makes it or what its called for sure but try google???

What llajumpvid said is all that I could find with advice for you on this one.

Welcome to the club though!

Well, I got the video working just by giving the "FES ON" wire 6 volts. Still no audio though. I found the FES left and right audio wires and put on RCA connectors and plugged them into to the AUX IN on my AVICZ1. I thought I was in good shape but unfortunately - no audio. I have my steering wheel controls working. This vehicle is a biatch, its almost worse than my silverado. I'm gonna have one pissed off customer if I can't get this audio working. Does anyone have the full wiring schematic for the FES plug that goes into the factory radio?????

In case anyone is wandering, I finally got this whole thing woking. I had to give the "FES ON" wire 5 volts, this will enable the audio from the harness behind the radio and video to the monitor. As for the factory infrared transmitter, I couldn't get that to work but solved the problem with an aftermarket IR transmitter which is getting its audio signal from the FES harness behind the radio. I also couldn't get the dvd controls that are mounted in front of the screen to work, but the remote still works. Also, the rear AC controls work fine.

That's good to hear.
