I'm stumped: My reverse camera feed is black after swapping the JBL MFD for a Pioneer AVIC-W8400nex with Maestro RR interface on my 2015 v Five w/ATP. Does the 2015+ / ATP require a signal wire to the reverse camera that woudn't be present in the earlier years or non-ATP cars? The reverse view worked fine with the Toyota MFD, The Pioneer head unit switches views to reverse mode when the car is put in reverse, so it's getting the shifter signal, but no video signal, Doing a similar swap (Pioneer AVH-4200nex with Maestro RR) on my 2012 v Five (non-ATP/JBL) was seamless, but that was 4 years ago, I've reflashed the Maestro RR twice with no change. All other functions work fine; I'm using the HHR-TO2 vehicle harness and the PIO1 head unit adapter pigtail, along with the "A" camera harness. Any advice would be appreciated. Thanks!
