I don’t know if this has been posted yet but I have a 2018 F350. I turned off the truck and the radio wouldn’t turn off and the dash was completely black. I turned the truck back on and no dash lights or needle movement. Turned off the truck and the radio still wouldn’t turn off even with the door open. I pulled the battery cables to reset everything. And now it works. It threw no code. Does anyone know what makes it do this.
