Try the following combinations to try and change the Area setting:

1 through 6
Repeated presses of 1
+ or -
< or >

Same problem with my Radio: I can get into the Settings Menu but the only available Area is EUROPE, pressed 1 -6, +/- and other keys but it seams there's no way to get USA...any idea ?

Tried multiple presses of eg Button 1?

I'm not sure but it may be that some models of the BM54 are locked to one area.

Correct me if im wrong but are the BM54 only for European models.

Hi, yes radio is installed in a X5 2005 European model (3.0D) , temporarily in the USA...and also yes tried pressing several times 1 but it seams there's no way to get it out of EUROPE (sigh...).
