Just got my new 2019 530e on Saturday and went to find some info on how to install a radar detector, and tap into the mirror like I had done previously on my i3 and M4. Couldnt find all the right info so I made a video. If you tap the right wires it should turn off automatically after a few minutes.
It was my first youtube tutorial video on cars so cut me some slack. I'll be posting a bunch more videos in the near future when I add my dash cam, phone charger, system, rims ect.....
