1400 miles on my 2019 Sierra SLT 1500 with the 6.2 and X31 package.
This black out to the infotainment screen happens on a regular basis. I have to turn the truck off and on several times to get it to work. On occasion the back up camera won't come on. I get a blue screen with a notice to service it.
The dealer has up dated the software twice and will no resolution. I'm waiting for my third up date.
The technician warned me it coul take a year or more for GMC to get these systems working right, yet they are still putting the same non functional units in the 2020s.
In addition, the system will not hold camera set up menu. I have to turn on the front camera manually every time I need it to park.
