I just removed my AVH3200 BT & U220, and installed a X930BT and used the same wiring harness.
The AVH3200 BT worked flawlessly. The AVIC X930 BT works nearly perfectly. The only issue that it has is that the lights behind the buttons are out. EVERYTHING else works perfectly. The LCD Screen, navi, and everything are functioning well, but just the background lights are out around the knob. I hooked the unit up on my bench and the lights came on, but not after i installed it.
I figured that the hookups were the same since the plug was the same.
I'm wondering if the AVH3200BT does not need the orange wire hooked up and the X930BT does... I wired the AVH3200 4 years ago, so I don't remember if I hooked it up or not.
