How can I reset my Blaupunkt PF3/C car stereo?

Go for a long drive and leave the radio on. After an hour or so, "CODE" should reappear.

You have to switch it on as you should when entering the code ( is it AS button plus ON switch) and leave it UNDISTURBED for 11 HOURS. This will rest it and then you can enter the code and press AS.
If it switches off automatically before 11 hours, then you will have to take it out the dashboard + wire it up to a battery on a workbench ( plus wire the speakers) and leave it for the 11 Hours
