I have a 2017 Z71 diesel that has been giving me glitches on the center screen. I get a loud buzz, then the screen blacks out, and in about 30 sec the Chevy symbol pops up like it’s starting up for the first time. It’s hitnor miss if my blue tooth pairing syncs back up or completely drops all my paired devices. Dealer updated the software (no fix), then replaced the HMI cable (no fix), then the whole display (no fix), then an amplifier, still does it two to three times a day (about once every 10 min). They dealer gave me a nice 2019 zr2 gasser to drive while they fixed mine up, and the day I went to turn it back in and pick up my truck, that truck with only 300 miles on it started doing the same thing. Anyone find a fix?
