You need an NBT EVO - HW4.1 is probably best & one with the blue GPS plug will make life easy.

Do you know anything about retrofitting this system or BMW coding? If not, many on here will be able to offer services to code the headunit to your car and activate.

Regarding screens, if you buy the headunit I mentioned above, then you want an APIX 2 screen - from a car made after 07/2016, youll also need the LVDS cable from the HU to the Screen as I don't believe the one on you current system is compatible.

Other issue you'll have is that your car does not have the correct wiring to be able to activate it, known as OABR or ETH wiring, so you may have to send the unit to someone to have this done or buy one from the many on ebay that are pre-coded to your car already.
