How to enter a Blaupunkt radio code
Radios sold under Blaupunkt's own name, with numbered presets and a serial starting BP on the label. A Blaupunkt radio built into a Fiat or a Nissan at the factory takes the code differently and has its own steps.The Canberra RCM 85, drawn from Blaupunkt's manual.
Type it and every step uses your own digits. It stays on this page.
Switch the radio on. The display shows CODE, then 0000.
Every step
Checked against Blaupunkt's owner manuals for the C30, Calais MP48, Canberra RCM 85 and ACR 3251.
If it locks
On the C30 and Calais, three wrong codes lock the radio for one hour. Other models show CODE ERR and make you wait. Leave the radio switched on for the whole wait: switching it off starts the wait again. On the Canberra RCM 85, 20 wrong codes bring up SERVICE and the radio can no longer be unlocked, so do not guess. What each lockout screen means
Built into a Fiat, Alfa Romeo or Lancia?
That radio takes one press per digit and has no confirm key. Fiat Blaupunkt steps
In a Nissan Micra or Note?
Those have their own steps, and the two confirm with different keys. See the Nissan radios
No 0000 after CODE?
On some older models, such as the Canberra RCM 85, press preset 1 once to bring up 0000.
Keys marked FM-T, AF, TA and M-L instead of presets?
On the ACR 3251, press FM-T briefly to bring up 0000. Those four keys then set the four digits, and the arrow key confirms.
