I just got my 2020 Z4 M40i and too am trying to figure out how to power a BlackVue dash cam from the fuses in trunk. I'll be using a Power Magic battery to power the parking mode. There room in the trunk where the battery sits for this extra battery. Just can figure out yet how to run the wire from the trunk to the cabin where I'll route it behind the window and door trim.

Attached are some photos of car, trunk space under carpet panel and the right side fuse box. Also is a fuse chart (a work in progress). Any changes or suggestions are welcome.
