Hi to all. I'm a newbie on this site, and it's come highly recommended. I have a 2003 S Type R Black. The car is fully loaded, except that it's fitted with the factory NavMan option. I want to retro fit the touch screen factory option. I've sourced all the necessary parts, plug's and cable. The one thing I can't find, and it's my weakpoint, is a clear wiring diagram. I would be most grateful if someone could help me out. I've been told that it's possible to manufacture a stand alone plug and play loom, but i'm finding it almost impossible to find a diagram. here's hoping.....
