I've got a 2017 i3 and some black spots have shown up on my nav screen.
I've never wiped it with liquid of any kind.
I guess there's a slight possibility that something splashed up there, but that seems remote, too, honestly.
I've tried wiping them with a soft cloth, but nada.
There were two and I just now noticed a third. Boo.
Has anyone else had this happen?
