Thanks for your help.

Can you please clarify what you mean by this.

Have just purchased a 2007 130i - Japan import. None of the instructions we have found on this site are applicable to changing our radio to extend the choice of NZ frequencies. Would anyone know how to do this yourself without using band expander. We understand that the radio could be an international one, and should be able to be changed. Anyone's help would be most appreciated.
