2009 Forester Auto- NonNavigation Reverse wire

Post by Cervera »

I've done many radios in the past along with remote starters etc so pretty okay with this stuff but I'm stumped...I went to install a Pioneer- Avh-4201nex on our 09 Forester along with a Pioneer Backup Camera (ND-BC8) using a maestro rr and SU T-harness. Everything looked good but the radio's screen would not flip over(trigger) to the reverse camera screen when putting the car in reverse. I did connect the purple/white wire from the hu to the purple/white wire on the SU T-harness. Is there anything else I have to do? Do I need to tap any wires from the kick panel or should I be receiving the reverse trigger from the t-harness which is connected to the factory radio harness? I did set the radios setup menu for the camera to detect on +. so the radio should be trying to detect it correctly.

I assume the camera's power/ground do not have to be connected in order for the radio to be triggered into the reverse camera screen, I should just get a black screen....correct?

I see also that the obd connector has a purple/white wire with a pinkish connector....does that have to be connected anywhere? It says it's for a manual transmission but my car is automatic.

I ran out of time so couldn't take out my multimeter to troubleshoot but will continue it soon and looking for ideas......

I also assume I can feed some 12v power to the reverse wire on the radio and see if it triggers the screen to change and that would rule out a defective radio..... correct?

Any help/ideas are greatly appreciated!!

looks like you are on the right path. before we start heading down the wrong rabbit hole let us know what you find with your meter on the purple/white. Thanks!
