Retrieve the serial number via P.SCAN+RDS
Hold the "P.SCAN" and "RDS" buttons (or "SCAN" and "RDS") simultaneously for a few seconds while the radio is on. On Chorus II, Concert II and Symphony models the AUZ serial number will appear on the display. Note it down in full.
Remove the radio (if display does not work)
Cannot retrieve it via the buttons? Insert four round DIN extraction tools into the holes on both sides of the radio and slide it 5–7 cm forward. The AUZ serial number is on the white label on the side or top: starts with "AUZ" and is 14 characters long (e.g. AUZ1Z41234567).
Enter the serial number
