I am hopeing you will be able to help me I have a UK 2004 X3 which does not have bluetooth prewired. I to have a Nokia kit which works fine but have also purchased a cradle and eject box for the centre armrest. The eject box has four wires, in a 18 block connector pin 1 Green pairing, 2 Brown Neg ground, 13 White cradel on, 5 Red 12volt supply. (This information has been found on this forum. I have tempory connected the red and brown up to the cigar lighter but it does not charge the phone do I have to link 13 to 5? and would I be able to connect up to the wires on the 6CD changer that is in the armrest. I know this is a old thread and hope you still are a member.
