Hi, I have an 03 plate Peugeot Expert and have

Your radio is made by CLARION and the only CLARION code available for free (using a serial number ) from anywhere on the Internet is if your radio also has a BARCODE SERIAL NUMBER beginning with C7000000 + + + + on a label somewhere on the metal casing.

(There are usually two barcodes on one label. The one required is the lower one )

There is a 20% chance of you having this barcode Serial Number

If not then unfortunately it will only be available from your Main Dealer or a Decoding Service
