As stated previously, CLARION radio codes are difficult to calculate .
If any of the serial numbers that you have given are in the form of barcodes then the code calculates as follows
Try 4654......if not try 4362....if not try 1644.
Please post back here whether successful or not.
If none of the above work, then I`m afraid you will have to try one of the professionals on Ebay or search via Google....but it won`t be free.
