I'm having similar issues, Mine is a 2015 Silverado, the 8inch screen goes blank, the steering controls do work, so I am able to tune the XM on favorites only through the DIC in the center of the cluster, one time I was playing a CD, there was no way to switch media. The backup camera works, I do notice the screen "dimming" and getting brighter....The Bluetooth no longer sync's with my I-Phone. I also noticed that the "phone" icon is not lit up, (so you cant press it and connect it). When it's out none of the stereo control buttons on the unit work...volume, power ect...I've had some weird displays show up several times. I called my Service Guy.. I'm waiting to take it to the dealer, I might try the battery disconnect, but I'm thinking it won't fix this. My Service Advisor said they need the truck so they can reproduce it at the dealership. Not happy about that. I have pics of the screens They read stuff like " STATUS: Initializing... Please wait! Searching for medium with valid download data. Then STATUS: Update Failed! Insert update media and remove others System is shutting down in 266 sec. There is a red box with copying 0/100 then the seconds countdown and it goes blank... I cant seem to upload the images... Any input?? or is it time to take her in???
