What am I missing? Got the recommended harness (XSVI-9005-NAV) but I am getting no power to the stereo when I connect the harness and stereo. I double checked the connections and they are solid (red/red ignition and yellow/yellow constant pwr). I saw in some other threads the older 9003 harness had to be modified to work but I haven't seen or found a thread saying there was an issue with the 9005 harness. Anyone run into the same issues? Oh and I have a 2016 with audio 15 with Becker head unit.
