Siemens VDO CDR 500 Code from dump

Hi all,

I have lost the code of my VDO CDR 500, and while messing with the car fuses I did a hard reset of the radio and is now asking for the code -actually I have a card with a code, but it seems some of the previous owners changed it…… 🙁

I made a dump of the 24c16 eeprom of the radio, but I don’t have a code calculator. I need help to either get the calculator or the code itself.


PS I am not able to upload the dump file, either as hex, bin, zip or rar… Any help?
