First let me say that I LOVE this headunit! My sister bought it for me last month (late B-day present) My Subie has a factory backup camera that worked just fine with the factory head unit. My factory camera didn't work with my new headunit but I didn't investigate the matter because I purchased a backup camera upgrade AHD 1080p Backup Camera. The issue I'm facing is that the harness that I have to use with my Subie is the "K Connector" There is no "Reverse" or "Back" trigger wire for the backup camera from this harness. However the diagram shows pin #2 as being the "Reverse" on this connector. From the K connector I have tried the "Brake" wire and I also tapped into the #2 pin the diagram shows as being the "Reverse". No luck. I also tried the "Brake" wires from the "G connector", nada. The only way I have been able to get a signal from the new camera is by using the "CCD+12v" , which i believe is meant for a front camera but it is working, kinda. Is there something I'm overlooking?
