I have a 2013 Nissan Rogue with the in-dash entertainment system (not the new connect system). Since I updated my iPhone to iOS 8.1, the USB audio hasn't connected reliably. When I first updated to 8.1.1, it worked for one afternoon, but then it went back to either not connecting at all or connecting for about a second before showing an error on the car screen and disconnecting.
Does anyone know if it's possible to fix this via a firmware update? Can you even update the car audio firmware on an old Nissan?
