2020 2SS without Nav.
Yesterday there was an update, I let it go, at about 50% the screen blacked out, didn't think anything of it, left the car and went in.
Today, the screen works (backup camera, environmental controls, but I can't get to any icons on the screen to control anything else.
I pulled the negative battery cable for about 20 minutes but didn't help.
Any suggestions (short of taking it to the dealer?)
