SD Card Removed Error - 2021 Yukon

[Seand442]

Looking for some final guidance before I have to break down and go to the dealer. 2021 Yukon SLT has been giving the obnoxious “SD Card has been removed” error for quite a while. I have tried new cards, multiple sd card readers, popping the sd card in my laptop to repair it, even took a look under the psgr. Dash to see the hmi box, but didn’t quite know what I was looking at. Is there anything else that I can do, before I break down and go to the dealer? It’s not much, but every time it pops up in the cluster, I want to put my fist through through the dash.
