Did some coding today. Added compass on instrument cluster and xdrive menu to idrive.
To display compass in instrument cluster :
KOMBI => FZG_AUSSTATTUNG => 3003 => KOMPASS_GRAPH_ENABLE => activ (I only had to set this)
KOMBI => FZG_AUSSTATTUNG => 3003 => KOMPASS_HIMMELSRICHTUG_ENABLE => activ (THIS SETTING WAS NOT NECESSARY FOR 2015 LCI 640i GC, its not present)
