I have an Pioneer AVH-4100NEX, and everything has been working fine last couple of months. All of a sudden, when I plug in the USB on my phone, the head unit doesn't detect it (it still charges my phone through the head unit so I know the connection is there) Even if I launch Android Auto manually on my phone (Nexus 6), it loads as if it's not connected to a head unit. Bluetooth audio/phone connection to the head unit still works. I rebooted the phone but that hasn't helped. Anyone else having similar issues?
Also, is this the best place to post about this? I wasn't able to locate Pi
