okay so i you been reading, the fuse filter box had blown, which had black, ornange and red going in it and out, on each side was a 1 amp fuse holder( i put 2 amp in) and a 7 amp the other side. so i cut both each side, and connected them up, tested them with the mutli meater, 12 v engine on, 14 volt engine on, but now the headunit dont rembear the settings, the only diffence is the black box has gone, so i headed down to maplins to find a replacment and there said it was a transformer, i asked what it was doing in the car and he didnt have a clue, so it did somthing to rembear the settings or make the battery wire or ornage wire as it is, my wirring can be confusing, some colours dont match, it plugges wont rembear.
