It might be VGA, but at what resolution and refresh rate? Is he going to have to write his own video driver for the LCD? Is the LCD going to be able to display anything other than the resolution that the nav system was desigend for? If, in fact, it is VGA, is there going to be a connector accessible? Will he have to cut open the nav system to get to it? Will he have to solder his own 15 pin connectors in? What if there's one thick cable running to the LCD screen that includes power and video data? Will he have to cut it and patch into it?
I'm not trying to flame you. Your ideas raise a lot of questions that you don't answer. If you do know what you're talking about, please try to write more clearly about it.
