Mine works fine, set to IP Bus your video output comes from the osd rca going to the D2 AV-Bus, you need to use 3-pin on the AV Bus.
Pin 1 = Video Ground
Pin 2 = Composite Input from OSD RCA Connector center pin.
Pin 12 = AV ON INPUT needs to go to +12V. The 12V input tells the AVIC to turn on the AV-Bus input.
