I didn't realize how well executed this was until after I ordered. I've spent some time looking into the details to see if I can "somewhat" easily retrofit it in my '13 335i.
On cars with lane departure, HBA is achieved with the KAFAS camera and KAFAS controller. For non-lane departure cars, with 5AC HBA as a standalone option, there's a unique rear view mirror which houses BOTH the FLA camera AND FLA controller.
My thinking is that it may be as simple as a mirror swap and some coding to enable this. The fact that it's such a cheap standalone option seems to support this theory. Has anyone else looked into this or run across any switches while coding their car? I should probably start a new thread...
