Hard wire dashcam
i am trying to tap into wire in rear fuse boxes power a dashcam, I used no 71 but this causes a lot of interference with radio reception? Removed it and radio now perfect, Tried 46 but camera stays on even when I’ve locked car and left it, ideally I want it to come on with ignition and turn of when I leave the car, does anyone have any idea what number fuse in rear I should use?
pits a 2009 c class w204 c200
thanks in advance for any help
