RESOLVED... Turns out that these stereo/dvd players with the 6"-7" screens can be a pain in the ass to wire up right if your going to use the back up camera and using the "proper installation" instructions which tells you to hook up a certain wire to your parking brake switch that only allows you to use the stereo while you are in park and the emergency brake is in place which is dumber than hell but it's for safety reasons. If you want to bypass that simply tied in with black wire coming from the head period then at least it will work all the time. Here's the golden shit. You have your yellow wire for constant power red wire for turn on with your key. What I did was tied the red wire from the deck to my fuse panel and tied it into the ignition slot with a fuse and it all works again! I will post some pictures when I get some time

What do you have the yellow wire hooked too?
coming from the deck? all those wires are color matched with the harness /interface chime box

If the fuses are all good, and you have +12 on the memory wire and also the main power wire.

Ground appear OK?

I'm not sure about that connecting the wire things together, never had one of these decks before. Is that a documented way to clear the unit?

yeah i didn't mean clear the deck by doing that i just threw it out there cuz it was wiring related. I'M going to call Pioneer tomorrow and see about a possible reset or common related internal issues that might have surfaced... I apologize for rambling about the PCM stuff, i mis read your question

i connected the battery terminals leads together. kinda documented i guess... I've done some diagnostics and monitoring of my PCM systems that had logged results outside manufacturers recommendations and followed up with that technique & run diagnostics again & and all previous data entries or the "memory" were wiped clean... It doesn't work every time but I've had more success with it getting my stuff runnin better than it had been previously. Beyond that ya know i didn't even think of checking the ground i just started testing for juice. i dug out some schematics on the factory radio wiring tho and power is where it should be. ill have to maybe see if a ground splice was disrupted or something next time i get a minute.

I will add For what it worth that i disconnect the battery terminals and connected the + & - together. i did this because it clears any stored data in the PCM like shift points air/fuel ratio / MAF, 02 sensors etc.... Starting fresh more less but I've done this in other vehicles and the stereos have been unaffected by the process.
