Will check Jberger. 3rd party charger test makes sense. You don’t want me to run a long cord? That was to screw with Ernie. However iPod or USB is not an audio option on my truck. 2015 Colorattle. White w/black interior.
The port on those trucks(And just about every GM vehicle for that matter) are set up for a radio that CAN use audio from the USB port. the fact that your radio doesn't do it is academic, the phone is still seeing it as an audio available connection and switching to the Lightning output for audio.
Get a cigarette lighter USB adapter.
