All of a sudden my infotainment screen started to jitter. Used the car last night and no issues. Got my C7 in October, 2013, VIN 00022 and have not had any issues since I got the Vette.

Anyone else have this issue?

Common problem. Couple of software fixes released but does not fix all. Mine does it occasionally on my early built car (built date: 9/29/2013).

Someone wrote that GM is now replacing the units that do this. Although I am pretty sure the dealer would replace mine, I really don't want to drop it off at the dealer for a couple of days. They already have work on this issue 3 times but since it doesn't do it alot, I am living with it. When it does, I video the screen with my iPhone to show the service manager exactly what it does.

I've had my C7 for about one year and one month. The infotainment jittering started happening on mine two days ago, VIN 11,808. It's doing it daily. Doesn't stop the music though.

I made a video on my iPhone to show the dealer since it probably won't happen when I go in for their diagnosis.

I noticed when I key up my GPRS 2-way radio close to the screen, it goes crazy.

Mine started jittering back in December, finally got to the point it would black out for extended period of time. Dealer had the car for a couple of days to consult with Chevy Techs. Ended up replacing the screen (replacement screens have new part number). No problems with the new screen. Vin 7299 (2014)

The screen in our C7 3LT started to roll intermittently in the last couple of weeks like an old TV with bad vertical hold. We have a little over 13,000 miles on it. I did a search at ALLDATA.com and found the attached bulletin. Gave info to dealer and they are ordering new screen.

Thanks for the attachment.
My screen has flickered off and on for a while. I found pushing the actual screen up to make a better connection stopped the malfunction for a while.
