OK I have a 2019 Chevy Z71 RST model I purchased and took home December 27th 2019 with 176 miles on the truck. At night time sure enough, I pet the truck in revers to back in my driveway and I have this HORRIBLE grainey / Pixelated display and on one occasion the camera cut out and went back to the normal display screen. I took it to the dealer on January 27th 2020 with 865 miles on the truck. They had the truck for three days to inform me that they could not reproduce the problem and that they compared it to other similar vehicles and it is operating as normal. They also told me that I DO NOT HAVE THE HD Camera. (I though the RST had an HD Camera) They also told me there was no FACTORY HD Camera I could add to my truck. Because the rear camera's picture quality is so BAD it is useless and when I went to just turn off the screen so I couls see out the mirrors with out the interfearance of the bright screen light, it appears that Chevy neglected to provide the ability to turn OFF the screen...... It's hard to believe that Chevy does not have access to the same camera technologey as other vehicle manaufactures or a too cheap to provide all of thier vehicles with a quality camera in light and dark conditions, especialy in a $46,000 truck. I want this issue resolved!
