I bought a Pioneer MVH-1400NEX and I got what Crutchfield recommended for the required adapters. I got the Maestro ADS-MRR and the HRN-RR-TO1 adapter. According to the maestro instructions, there should be a 16 pin harness that I connect for the rear camera to integrate with this head unit, but it does not appear to be there. I have a few extra cords remaining and my display says “Check Hybrid System” and anytime I go to shift out of park it tells me to shift back to P Position. Any ideas of what I could be missing?
