Which units it applies to

  • Volkswagen Group radios labeled RCD 200 / RCD 300 and some Blaupunkt-branded head units used in VW, Audi, Seat, and Skoda vehicles.
  • Early Blaupunkt models that use the same security-code algorithm as factory VW radios (commonly known as “Blaupunkt 1” in tool/service lists).
  • Not all Blaupunkt models share the same algorithm—different families and later-generation radios may require different procedures or manufacturer support.
  • Use a permanent marker on the top of the radio chassis.
  • Tape a business card with the code inside the glovebox.
  • Save the code in your phone's password manager (e.g., "VW Radio Code: 1342").
  • You may have a Delphi unit. Check the sticker on the side of the radio. If it says "Delphi," the Blaupunkt calculator will not work.
  • You may have a Blaupunkt Type 2. Look for a serial number starting with "BP" only (no VWZ). You need a different tool.
  • You misread a character (e.g., 8 vs B, or 0 vs O). Retrieve the serial number again.
