I too had the flickering screen issue and took it to the dealer for service last Wed 3/18. They thought perhaps the GM recommended software update was the fix but since then I have noticed a couple of issues:
1. As I was driving home from the dealer I turned on my XM and it did absolutely nothing. I mean the AM worked fine and the FM was fine. (No trees or overhead obstructions to block the XM signal and the subscription doesn't renew until May). I turned around and took it back. They looked at it (outside of the building) and while they were looking at it the XM magically came back on. I drove home with it without further issue.
2. Today (Mar 21) I took it out for a drive. Initially when I got in the Corvette logo flashed on the dash and the infotainment screen like it normally does but after I backed it out of the garage I noticed the infotainment screen was dark/black. I tried the radio and could only get AM and FM. After a little driving the XM returned but the screen was still dark/black and the backup camera display didn't work either.
Since the dealership service is now closed (closes Sat at 1 PM and no Sun work), I have submitted my online request for a Mon AM service appointment. Mine is an early 2014 not sure if it matters or not. The software patch was to bring it up to current. I will update when I know more.
this is strange my 2014 z51 just started to flicker this afternoon. i read where you just lightly honk the horn and it goes away. i tried it and it work perfectly. anybody knows anything about this? should i still go get a new screen anyway?
