Hello, I was wondering if there is a fix for the infotainment system not turning on at start up just Black Screen??? I purchases a 2020 Sierra Denali 2 weeks ago and on day 3 the infotainment system wouldn't come on. There was no radio, no cameras, just absolutely nothing. I was like really this new and happening on my 3rd day of ownership. Now yesterday I remote started my truck and I got a Black Screen again around 3pm and I went to go out again at 7pm and got Black Screen. So I went inside my place and waited 6 minutes then went out and it came on were I had a fully functional infotainment system. The first time it happened went to a store then went in and came out 10 minutes later and unlocked the truck, opened the door and the screen came on. So this shouldn't be happening in 2 weeks of ownership!!! Is there a fix???? Thanks
