Hi all, just purchased a 19 plate M140i, so LCI2 I believe. Its got everything I want bar the pro nav. I read somewhere the LCI2 cars have the same head unit regardless of it being the large screen or not. In theory could I just replace the screen for the larger touch screen one, and the I drive controller for the touch wheel type, then I would have Pro nav, including apple car play or do I need to upgrade the head unit too, obviously some coding would be required I would imagine?

Cheers
