I'm trying to replace my non-nav Bose head unit with a Sony xav-ax100. I've got everything going with the PAC, etc but I'm stuck in the OEM camera. I bought the AX-MAZCAM adapter, but it doesn't fit any of the plugs from the factory. I believe I've located the harness for the camera and it has 5 wires. white/red, white/blue, white, and two dark blue. I popped the trunk panel and found the backside of the camera harness that had white/red, white/blue, white, and a braided silver. Any ideas what the pinouts may be or how to wire to the AX? Thanks!
