OK so Iv had the idea that I want to hard wire my GPS to the lighter socket to save having the wire and big ass socket sticking out of the dash. Now Iv had a quick look about and it seems I shouldnt just cut of the end of my cable and tap it into the lighter wires as this provides 12v and most GPS's run on 5v or there abouts. I would howerver want it to cut power to the GPS once the ignition is off. Any thoughts? Thanks
