Videos of this in action:
Note that this retrofit will be offered for all F series vehicles (M and non M) with KAFAS2 - not exclusively for the F85/F86 but also the F10 M5 and F06/12/13 M6 as well.
You will see it lose lane detection a couple of times in the video, but 95% of the time it works very well when used as designed. For full transparency we wanted to also include this for viewing.
