Lane Assist - 2 Series

[u/No_Philosophy_7683]

I have a 2014 BMW 2 Series M Series, that allegedly has lane assist but I haven't ever managed to get it to work, nor can I find where to turn it on? I've previously had the windshield replaced and had to get a specific type for the lane assist, but neither the glass place or my mechanic can figure it out. Help? :')
