Question about Blaupunkt Bremen SQR 46 DAB

Hello, I have the same problem, we can't get through Menu. How did you solve your problem?

So it works well for me once you know how to set everything :-) However, I don't use it that often because it's quite loud in the car and you can't hear the engine when the music is too loud ;-)
I have not yet had any problems with starting. Is the battery of the vehicle possibly too weak or not fully charged? Hold a voltmeter to the battery....
