2019 Chevrolet 2500 HD Duramax LTZ. These issues started several months/4k miles ago and have progressively become more frequent. Truck currently has 60k miles on it.
Note that I have performed the following several times:
System update (current).
Infotainment system Reboot (current).
Calibrate touch screen.
Infotainment screen:
Freezes. Will not respond to touchscreen touches(?). Home button & other manual buttons work including volume/channel knobs, HVAC controls & steering wheel controls. Was intermittent but seems to occur more now that warm weather is here.
Switches from one display to another. Ex.: Displaying radio info, display changes to the navigation screen. Then it will start scrolling the displayed map w/no used input.
Turning off/on the screen changes nothing. Turning off the vehicle completely resets the display (usually). Allowed to cool off completely does reset the display. Maybe heat related?
Instrument cluster screen:
When looking at the 'Info' screen, display changes to Audio display w/no driver input. Driver returns to 'Info' screen; system changes it to 'Audio', etc. See above to reset.
Any suggestions would be appreciated.
