I have a BMW business head unit in my e36.

Need to get code back into it after disconnecting the battery.
I have a book about it in the handbook but its in German!

Ive got the code and ive put it into the head unit but what do I press for it to accept the code?
I have tried pushing the "M" button after entering the code but it did nowt

TIA

You need to be more precise on the unit. Post up a pic of the front. Dont try any more times until you know the exact process, you might get fully locked out.
