1. Which port should I use in the fuse box (for an 08 m3)? I will be getting a Fuse Tap.
2. What/where (is) bolt or screw do i use to ground?

sorry if these questions were answered already

And to ground your detector, you may have screws above the console, use one of those. If you don't, you can use a self tapping screw and screw into the roof right beside one of the small holes already there. I did it and it works fine.

Didn't want to get up and get the camera.
