Need code or a guide for my bmw business radio

[waaski]

I have changed my. battery and I can't get the radio to work.

I have got the code 7048 from my garage but is doesn't work or I am doing something wrong.

I put the code in with the first four of the six buttons and then I used de -> button after that the radio ask again for
the code and after three times again code wait,

Numbers found on my radio:
BP8272W18300487842
FD 498
BMW Businessw CD 6512 - 9416 - 433
Index 10
It is a Blaupunkt.

Can someone tell me if the code is wrong or did I do it wrong way.

Thanx in advance

Thanx. But if 5873 is the correct code. I have tried it and I am still without music. The radio still asks for the code. Do I use the correct way to put it in?
