So I’ve recently bought a nearly unmodified 2017 LTZ 2500HD, no serious complaints other than the def system but that’s for another post. I have an issue with the radio/nav screen I guess you could call it “ghosting”, sporadically switching screens. Got a check in the mail from the dealer for replacement and labor for unit. dealer saying his service guys told him about it after the delivery to me. Anyone have this problem or know if the unit is plug and play?
