The Drivesoft Lite (which is software only) is only $49.00 ... I don't know about the hardware which brings us up to this thread ...

I know that there has to be some kind of GPS interface .. Sound Card ... Video Card ... etc. and all the small 'touch screen' monitors (7"-10") are about $650-$700. I think you can get away without the touch screen if you have place to use either a mouse or a trackball ...
