The other day I noticed that after the Chevy mylink image came up on the screen following turning my truck on, the screen went blank. Screen switches to back up camera when truck is placed in reverse. Some text popped up after being on for a while saying "initializing" and then "update failed." Dealership wants to charge $200 just to look at the truck so I am hoping to get my answer here. I have attached photos of what I saw. Thank you for your help!
