Can you please tell if replacing the video processing unit permanently fixed the camera problem because my 2020 Blazer RS has the same problem with only 100 miles on it and going to bring to dealer next week so i would tell them to test video processing unit before replacing other parts.The dealer replaced the camera on ours too. It worked for a very short time and then it stopped again. The dealer had a "specialist" from GM look at it and they had to replace the video processing unit. That part was on back order (does that mean it is a common problem?). 10 days later the item was installed and so far no problems (two weeks). The dealer has been very good about the whole issue.
