For #1, 2 and 5 (sorry, I don't have #4 and have never noticed #3 on my cruze), make sure you attached the ground wire with the loop on the end from the GMOS044 harness to an appropriate point on the new radio you are putting in. The documentation suggests the ISO screws on the side of the radio, which you would have to screw in anyway to use the dash kit. Put it in against the side of the radio before you screw the rest to it. Without that, a lot of the other stuff from the interface box does not work.
Also, is your relay hooked up or has a wire come loose? It's on the one bunch of wires that goes into the box.
If you need a pic later of any of this I can grab one.
