If your CLARION has any BARCODES on the outer casing, then ask another question quoting the numbers.
Also quote ALL the other SERIAL NUMBERS
If no barcodes then I don`t think anyone on these free Help BOards will be able to calculate your code so you will have to use one of the "professionals" on Ebay or search via Google ( It won`t be free though )
