My center console usb port stopped working earlier this week. I spent the evening following the wire and troubleshooting but I'm lost now and clueless. The previous owner set up the system and all I know is that the head unit is a Pioneer AVH-2500NEX. There is a USB extension port running to my center console but the usb is not working, and when I plugged a normal USB charging cable into the back of the head unit it also didn't work at all. No charging and no apple carplay functionality. Is my extension broken and I need some kind of new one or am I SOL and need a new unit. Any help is appreciated, I really don't know what I'm doing at all.
