Hello. I have a Citroën Berlingo M49 with the factory headunit - a Clarion PU-2294B(D). Didn't get the code, when I bought the car and it resat when I helped a friend start his car The serial number is CL0402Y0352127. Hope someone can help
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 or your local Car Radio / Audio Store who will connect a laptop to read/recode the memory chip (EEPROM) inside your radio.
