Setup: Pioneer 4400nex on 2012 VW Passat. Replacing a an Android headunit, with which I had already installed a back up cam and was planning on using the same one for this new head unit. Backup cam had been working perfectly, with power coming from an add a fuse tap in the fuse box. Using a PAC Rp4 wiring harness in the new Headunit. With new Headunit it successfully shifts to reverse cam input via canbus every time . Problem: it's a black screen no matter what I've tried. I'm plugged into the proper brown rca input.
