I own a 2015 GMC Sierra SLT Z71. When I put my truck in reverse, the reverse camera that pops up in the dashboard (the 8" touch screen) is black and says 'Service Rear Vison System'. Does anyone know how to fix this issue? It should be noted that I have not been in any accidents, have not replaced the rear reverse lights or head lights. I do have a LED brake light-bar underneath the tailgate that is plugged into the tow hitch on the truck. I have had the brake light-bar on the truck for almost 6 months now so I don't think that is the issue.
I just pulled into the driveway in my new sierra after about a week and on the instrument cluster where is shows my speed, there is 2 rows of a black bar about an inch in width. It looks like the pixels are dead or the display is dead in that area, however when messages come up it displays stuff there. it it just to the right of the 6k rpm reading in the main window. Anyone have an idea how to correct this?
