You waste your time. Car has ENTRYNAV (ROUTE) Head Unit, not NBT (NEXT) Head Unit. It has no DE File. PM sent.Hello I need your help please I have installed I want to remove the DE.fsc file from my NBT browser to be able to generate the update key for the Road map europe west 2022-2 and there is no way to connect my E-sys or BMWAI V3.4 with my F46 😮💨😮💨😮💨 it's a headache 🤒 but it's cool to investigate 😋😋 So if you don't mind, could you provide me with a BMWAI download link compatible with my F46 or else I'll leave you my VIN to request a key if you'd be kind!
