Sorry for the delay, was out of town for work. Touch screen locked up again, was fine for a little while and then got the service rear camera error message in R, lost guide markers and then everything started working again. Going to call dealer and see what they want to do this time. I'd think by now they would want me to go away and do whatever it takes to make that happen

So far so good, work log said the cable had a pinched wire and that was causing more resistance, dropping voltage between radio and display. I'll update next week if all continues to go well, if not I will update sooner

Truck was left at dealer for 2 days, replaced cable and did 2 recalls (alternator cable check and brake system),. drove it home and it worked. Got a call from GM customer care, offered me 6 months XM for free for my inconvenience so I asked they hold off more than a few hours to make sure it works before we throw out free XM (which I think you can still get for under $5 if you call and say you are cancelling the service) as a gift for my troubles

Cable arrived and I dropped it off, will update if that fixed me or not, ?

Getting the cable between the radio and the touchscreen replaced today to see if this resolves my issues with the blank screen/touchscreen not working.

I'll send you a message

No change with this for me, still having issues, still no cable at dealer. Its been adding to the symptoms if anything. Its really frustrating to lose the radio and display but losing the backup cam, flashing errors on the display and it simply going black for 30 secs to days? I can't believe this passed QA testing.

I think your issue is related, there seems to be various symptoms but all point to the infotainment system in these trucks is garbage. We paid damn good money for these trucks, they should work as intended not be jerked around at the dealer cause GM doesn't know how to fix their issue.

This is interesting, haven't heard or seen that before. I also don't have On-Star so I'm really screwed if that's it

I'm seriously slightly steaming over your response or what your dealer said, that is insanity! So far mine has been great, I've got courtesy vehicles for over 3 weeks, 2020 loaded ones even. They want to wait for the fix to comp me anything or offer anything which I'm not too pleased about especially after finding this site and seeing this isn't just a me and my truck problem. Weird thing is on these courtesy rides, no issues what so ever with anything. They said its different modules and the trail boss is different but one of the rides was a 2020 RST which I would think would be the same, idk. Coworker bought the same truck and has had zero issues so far which also baffles me. I'm not sure I fit the lemon law as its just a radio but honestly, GM and dealer would have been further ahead now to have sent me to a custom radio shop and installed some other brand radio, speakers, amps, a sub box, maybe some video monitors than to keep wasting all their time and money

Same issues as you all are having, started from day 1, I thought it was me as it was a CarPlay symptom initially, then I went to black screen, then touch screen, back up camera, etc... Is this enough for lemon law? I'm in it for 6 months of issues, multiple trips to dealer, multiple times we can't replicate it (I have videos from the time they told me that to prove I'm not crazy). multiple trips to pick it up saying it was fixed but when I started it up it was broken.

So this is interesting. What they want to do now is replace the cable from the screen to the radio, pin misaligned or wire broken is their thoughts. I'm confident this won't fix it, I think they have an issue with their code inside the radio but I can't prove it. Good luck to you, I'll keep this updated with my status, hopefully it helps someone else out.

Update- Just drove 3 hrs with a black screen, backup cam worked but no markers, no climate control indications when I changed fan speed or anything, hard buttons did nothing. Stopped and started, no change but I may have forgotten this on my original post, when I turned it off and opened the door, the screen displayed for about 1-2 seconds before it went black. then starting it back up, still was black

I'm not trying to be nosey but what did GM offer you? how did you pick a lawyer out? My internet searches lead me to some crazy sites, that remind me of scam/spam sites. What are you asking for in your case? What do you expect to get? Please feel free to private message me if you'd like, I'm trying to debate since all I have is a radio issue what its worth as far as my time and money.

When my radios and screen were replaced, I got up to about 2 weeks before I had any more issues, then more frequently I'm sad to report.

Bought truck in July and had infotainment issues from the start, the screen is black but backlit, the screen displays but will not work with touch, sometimes the hard buttons will move it other times not. The climate control changes sometimes will display, loss of back up markers, sometimes loss of back up camera with a screen error of connection lost, audio is lost sometimes, CarPlay won't always sync and I'm sure other things I am forgetting as well. Only has issues on start up, never going down the road so I don't think its a lose or broken wire, improper pin alignment. Sometimes it works, sometimes it doesn't. Its so random how long it doesn't work for, not very often stopping and starting will fix it, sometimes its a day or more before it works again. The radio was replaced at dealer, 2 weeks later it starts acting up again, dealer worked with TAC(?) to determine they were replacing the radio again, strike forced it to be delayed but eventually replaced, less than 2 weeks later same thing, then they replaced the screen/digitizer, I went to pick it up, started truck and screen was blank. Now after having my truck for about 3 weeks (this time) GM wants to try replacing the bus cable from radio to screen but they want me to not connect my iPhone as they think it could be causing the issue, even with video documentation showing my phone not plugged in and blue tooth disabled and 2 times with dealership mechanics seeing my phone in my pocket. My questions are - 1) anyone else have this issue? what was the fix? 2) What kind of compensation should I be seeking for 5, almost 6 months now of it not working right, repeated trips to dealership, long waits in lounge, being told it was fixed only to show up and it's not? I have kept extensive records for every time it happens, videos of probably half of the instances.
