Well I seem to have run into an issue with my testing. I have lost the ability to set many of the instrument cluster variables. All the options you get for the various parts of the display corners, sides etc. I assumed the Naviks unit was a likely cause so worked out a plan of attack with them to start trouble shooting the issue using both modules I have. To my surprise after working down to no Naviks harness at all in the truck my problem persisted. So it went in to the dealership yesterday to "update the instument cluster software" which they thought should fix it. Well I just picked up my supposedly fixed truck and it is exactly the same except it now has different values presumably set when the tech tested it. So since I don't want the Naviks unit in the truck while this gets sorted out for warranty reasons my testing is unfortunatly temporarily delayed. I don't know how long I have had this issue. My truck has 6400 miles on it with over 3000 of those with the Naviks unit. When you remove power from the truck the reboot that happens after you power back up resets lots of things. So I have just run my cluster in the rebooted default settings since my first Naviks install back in Sept. Since then a lot has happened behind my radio screen by myself and Naviks with lots of battery disconnects along the way. I have no way to know if my current problem has any relationship to the Naviks unit at all and for now I am assuming it doesn't. I am very anxious to get the unit back in the truck as all indications looked pretty good. BTW I asked Naviks about the 2019 they used to come up with the fix for my 2020. They said the 19 had the same issues as mine needing the same fix. During that discussion they indicated a file comparison of the 2019 and 2020 showed exactly the same 600ish lines of code with the only difference being the 1 vs 2 Aux inputs. Given that it seems like it would work for a 2021 if it doesn't change.
