I've been trying something different, I've noticed that when not having my phone plugged into the usB port on the dash using bluetooth only, I haven't had anymore problems so far, so I'm thinking if it's the cord or the USB port on the dash. More towards the usb port because when my phone is plugged in it still charges my phone. Still seeing what happens. I've just had 2 updates at once a few days ago.
I'm having the same issue with my 2019 Chevy Silverado crew cab custom 4x4 truck. I'll be driving down the road and the radio screen goes black, the back up camera will still work and sometimes either the radio or pandora driving or sitting still ot will happen. I went to the dealer and they said if it's under warranty no problem, but if not they want $130.00 for an hour to find the problem. That's a no can do for me, it should be no charge my wife and I have a 8 year bumper to bumper warranty plus we just purchased the truck on June 30th.
