It is possible to skip steps 8 & 9 by taping down the LCD to the board and cutting the "legs" off the green piece and inserting a rectanglular piece of coloured transparency in its place. This, however, will not look as good, though it is safer and less complicated.
Note: Make sure the clip attaches to the cigarette lighter panel or else the panel can fall during driving. Remove and replace the cigarette lighter to make sure the panel in being held in place.
Note: An Audi cigarette lighter casing will not plug into a VW. You must either change the wiring in your car or move the Audi ring over to the VW casing.
