Blaupunkt-built RCD 300 units are identifiable by:
This is a common anti-theft feature. The only way to revive the unit is to enter a four-digit PIN code. For many owners of the manufactured by Blaupunkt (specifically variant "1"), the search for a solution leads directly to a digital tool known as the RCD 300 Code Calculator .
If the sticker is faded or missing, you must read the EEPROM chip (24C16 or 24LC16) on the mainboard using a programmer like CH341A. This requires soldering skills. For most users, buying a replacement RCD 300 on eBay ($30) is cheaper than an EEPROM reader.
For technical users, the code can be found by reading the data from the radio's internal EEPROM chip
