Restoring CD30 MP3 from CarPlay aftermarket unit
Hello, sorry if this is a stupid question, first time replacing radio unit on my Corsa D 2006 1.2. Currently it has CD30 MP3 with GID display (bigger one). I bought a new unit with CarPlay because I had enough of FM transmitter terrible quality. My question is will I be able to switch back to my original radio unit if this carplay disappoints me without an issue? Won’t it require security code? Previous owner failed to provide me with CarPass card and having no security code might be problematic if it requires me to input it.
