Hey guys,Just wondering, now that Sapura + AB is offering navi retrofit for non-navigation bmw's.. The pre-facelifted E60's..Does anyone know the respective part numbers that they will replace when they do the retrofit?For RM28K, its kind of steep.If i can try to source some of the parts myself or second hand, i might be able to make it happen for less!HeheThanks for any help!Regards,Kenny
