Rear Camera - Not Very Clear?

I tried it all kinds of ways -  connected to my house wifi..  then connected to my phone hotspot.  It does the scan for updates but always says I have the latest version already  -  V507 from September.

Wait a few days and re-check.  I have not received updates, that others reported,  until a few days later.

I have a 2019 Colorado Z71....same isssue....camera is not clear....grainy...poor quality.  Dealer replaced the camera and harness and it did not help.  They are replacing radio in a few days and this is all they can do according to GM.  Radio is analog and it should be HD.  I believe all these cameras are SD and GM sold as HD.  Don't know how to prove it.
