More time on Sunday and Monday seem to have paid off nicely - I tried to take a short cut and use small plastic connectors to wire up the camera but the connectors never broke through the insulation so I had to strip it back and solder it proper.
So, I've tested the camera, FM stereo, and CD playback. I'm currently hung up on the iPod features because the unit won't seem to recognize my iTouch - I connect it and hear the beeps and see the unit start to charge but it constantly says "Reading ..." on the DNX9960 screen. Any thoughts on where I've gone wrong here? I can switch to Hand mode and simply choose music on the iTouch and hear it in the car but I can't seem to actually control the iTouch with the HU - HU firmware is 1.4 and iTouch is 1.1.5.
Still left to test is connecting my phone, Bluetooth hands free, Navigation testing, USB music testing, DVD testing, goodness will it ever end.
Not to mention I have to tune the subwoofer and put all the panels back in place.
EDIT: iTouch is working now - this is a 1st Gen iTouch and I never upgraded to the latest iOS - I'm running 3.1.3 now and it is working great!
