Just to note that the cigarette lighter socket needs to be one of the fully insulated 'stand alone' sockets, then it doesn't care about positive or negative earth, it just works on 6V difference.
Been using one from Maplin cost £2:99 for about 10 years on a number of Tom Toms. Wired as noted above just to convenient supply and earth. Mine is hidden in the glove box, wired from behind so it cannot be seen but sat nav can easily be plugged in.
All with usual caveats that some have previously said that the lack of voltage regulation has blown sensitive electronics in sat navs especially on starting surge.
