Going from an aftermarket head unit to oem.
I know this sounds crazy but I’m going to go from an aftermarket head unit to an oem head unit. I already have an oem unit ready to go. My big question though is whether or not I’d have to cut the wires and splice in an oem pigtail? I currently have a double din CarPlay unit so I think I’d definitely have to put an oem amplifier in to make the old unit work again. Anyone have any advice for going this route? There’s only videos or write ups of doing the opposite.
