I was just wondering if anyone has ever considered the possibility of adapting a nav screen from a 7" GPS such as the Magellan Roadmate 1700 (7" 800 X 480 that looks very sharp and works well in sunlight) for use in a carPC, perhaps in conjunction with an existing touch screen monitor? As in, use the signaling from, say, a Liliput or Zenarc to drive the Mag's panel? Is such a thing possible?
