You’re going to need to purchase and inject an FSC code. Honestly it’s not as straight forward as just checking a box and coding unfortunately.
Initially I purchased a usb download for my car (don’t remember the istep level). All I had to do was insert the usb and restart the idrive. This gave me only split screen capability. For full screen I paid someone to update my idrive and recode.
Also a 2017 car. I ended up using bimmer-flash (was able to setup Esys using my flasher dongle) and allowing them to remote code and install everything.
