I know this is OT but I'm hoping somebody on here can at least point me in the right direction. I just got a Lincoln MKZ which has a dvd based navigation system. I was wondering if anybody knows of a hack which will allow me to put a movie DVD in place of the Navigation system DVD and watch it. It seems like it would be feasible given the hardware but would require some sort of firm/software hack. Does anybody know of a fourm related to these sorts of things?
