Your radio is made by CLARION and the only CLARION code that can be calculated (using a serial number ) anywhere on the Internet is if your radio also has a BARCODE SERIAL NUMBER beginning with C7000000**** on a separate label somewhere on the metal casing. (Note ...not beginning with CL.)
If not then it will only be available from your Main Dealer or a Decoding Service will read read/recode the memory chip (EEPROM) inside your radio.
