I decided to see how much of a pain it would be pulling the radio/CD and installing the monitor. I found some instructions on how to get the radio out a while back when my CD changer was acting flaky. There are no external screw, you have to pop the upper air vent assembly out. There is a tab behind the unit. I wrapped a butter knife with a single layer of t-shirt and inserted it where the red circle is:
Once the vent starts to pop out, you can see the tab that secured it.
Pull the vent assembly out and you can unplug the power to the clock. Next there are two screws to remove to get the main trim piece off.
Loosen the screws and pull lightly and work the trim piece loose from the right side. Once it pops out, you will need to move the shifter to L and swing the panel out. The assembly at the bottom can be popped out and plugged back in, as can the flasher and defrost buttons on the top. If you plan on driving, you need the flasher assembly plugged in to use your turn signals, although nobody in Atlanta seems to actually use turn signals. I'm not sure if the 4WD selector needs to be plugged in to drive, but why chance it? Once the trim is out of the way, we can see the four screws that need to be removed in order to get the radio and CD changer out.
Remove the screws and pull the unit out. There are a lot of connectors.
You can safely unplug all of them. They are unique and can only go in one slot.
With the units removed, you can see the screws used to hold each unit in place. They are torqued down at about 5000 ft/lbs, or so it seemed...
The mounting holes for the monitor line up great.

There is something inside the front screw holes so if you use them, you can not get much more than 1/2 turn on the screws. If you run the rear screws in all the way, they will hit the side of the screen and will stop it from extending or retracting. I just put about 1 turn on them.
As I mentioned, I am impatient. So here is a shot of a ghetto install, note the power cables hagning out the bottom.
It works! When it opens and closes, it misses the shifter by about 3/8".

I can not move it to the top position, there is no room behind for the VGA connector or the USB cable for the touchscreen.
Now for constant power and running audio wiring into the HU. I am still trying to find a wiring diagram or pinout for the wiring that originally ran to the CD changer. I am hoping
mobileinformationlabs.com will also have the diagrams I need. I am also hoping the steering wheel controls are in the connector for the CD changer and I can use them for some sort of input control when computer is selected input on head unit.
This week, I hope to finish up the wiring and get this thing running.
