Monaco 172
Just swapped the cd head unit from my 172 into my old 1.2. found the code in the owners manual. when i entered it its just come up saying error, in the owners manual it doesnt say anything about an error messege just that if the code enrtered is incorrect it will beep and say code and i've got to wait a minite before trying again. is this correct or is the cd player knackered all of a sudden? :S
