Question: iPhone 7 Plus can’t connect via USB
Since the 11.3 iOS update my iPhone 7 plus will not connect to my 2014 Chevy Silverado WT1 radio via usb cord. I get “Cannot use Accessory. Only one accessory can be used at a time”. Problem is that there isn’t anything being used at the same time as the usb! I have tried turning off my Bluetooth, restarting my phone and trying different usb cords to no avail!
