Assuming you have legally extracted the serial number from your own radio:

Step 1: Locate your radio’s serial number.
Press and hold "FM2" + "RDS" (on Gamma radios) or look for a sticker on the metal casing. For AUZ1Z3 units, the serial usually starts with "AUD" followed by 11 numbers.

Step 2: Run the Repack Better executable.
Unlike the original, this repack doesn't require admin rights or disabling UAC. It launches a minimalist interface with a large text field labeled "SERIAL."

Step 3: Enter the serial.
The "Better" version auto-detects if the serial is for an AUZ1Z3 or an AZZ (a different algorithm). It will then output a 4-digit code. Critical: Always cross-check with a secondary calculator (like "VAG Code Helper 2.0") because repacks can introduce their own bugs.

Step 4: Enter the code.
Press "FM" + "SCAN" to exit SAFE mode, type the 4 digits using the preset buttons (1-4), then press "SCAN" again to unlock.
