I have recently purchased an m140i shadow with business nav LCI2 but looking to upgrade to the pro nav screen ; as the business nav looks odd in the car. However, i am unsure on whether i need just the screen or the whole unit. I have all the features on the business nav (bmw connected services etc) so would i need just a screen (and coding) to give me all the pro nav features? Ive added a pic to one i have seen online to purchase - any help would be appreciated.
