VABAM

With out seeing your work it is hard to diagnose the issue. When scope22 was having issues he posted pics of his wiring job (in the DIY thread) and I was able to see that he had wired it incorrectly. Post some pictures of your wiring job. We might notice something that you missed. Also post a pic of the AC auto amp part number label. Same thing for the controls.

My best guess with the info you have provided is you might have a bad part. Most of the parts on eBay are salvaged from wreaked cars so buyer beware even if they claim the part to be functional. Testing the controls and AC Auto amp takes a higher level of knowledge and test equipment that most people don't have. If your wiring job is good, the only route would be to swap out the AC Auto Amp and controls with known good ones or test your parts in Non-Nav Z.
