I have been using the usb to play pandora through my phone. Recently this no files found message appeared and it wont let me get to pandora. I can hear the music in the background but as soon as i touch the ok or turn the volume up it kicks me off. Its not my phone because it works in my 2011 silverado & my wifes 2018 terrain. I have an iphone 7s. Ive tried unhooking the battery terminal three different times. Ive also tried different power cords including the original one from apple.

What gives? It was working fine for months & all of the sudden now its not.
