I have searched but to no avail. The posts I did come across did not pertain to my current situation. I've been using my f90bt with numerous ipod and iphone generations and most recently the iphone 6 with no issues. All of a sudden my f90 is failing to output sound when the phone is connected. I can see the song currently playing on the screen, but no sound. I have the OEM Pioneer cable that CAME with the unit combined with the 30-pin-to-lightning converter, and have AV1 set to ipod. The f90 is on FW 2.0080 fwiw. any help would be appreciated...
