Hi i have a 16 gmc sierra im having multiple issues and can't figuer them out

First issue I hit my turning signal or even stopping. Will cause my radio/display screen to turn green.

Second issue is also in the display screen my backup camera won't come on when I'm backing up any help would be greatly appreciated!

if you have a trailer plug , take it apart to see if it is full of corrasion . check the grounds for your tail lights
