Newbie just got a 2013 S P85+ and wanted to install a dash cam on the windshield. Hid a 15’ mini USB (Amazon $9) cable from behind mirror to the 12v outlet in the center console. Took about 10 minutes to tuck it all through headliner/door liner and under passenger seat.
The key to note that although the two USB outlets stay alive after exiting the car, the 12v outlet does not and switches off the camera.
