Have had my 2017 Volt Premiere for one month and while using the Infotainment's Navigation and playing music from my iPhone with Apple car play, the screen went blank and all associated functions stopped working. No radio or backup camera, energy info, navigation, phone etc. The USB ports also went dead, but the DIC display was functional with the message, "audio off". I brought the car into the dealer without an appointment to have the fuse checked. It was normal, so they gave me an appointment for 1/10/2017 to diagnose and repair. Anybody have this problem? I'll post an update.
