BINGO! On the internet I found the advice to press the front panel. Then I saw the display asking the code. I used the code you gave and.....the radio is working again. Unbelievable.
Many many thanks, also from my wife who missed radio still more than I did.....

Many thanks for your fast help. But for the moment I can't check this code because the radio is "dead" now. Fuse is still OK. The code you gave differs in only one digit from the one on the car papers.
