NAV display for VGA (PC style)

[Ridgeline4wd_Archive]

OK, so I've seen the topics that ansewer the delema of adding DVD playback to your existing Navi screen.. Neat, cool, wow...

What I want, and what I consider would be the true killer-app here is the ability to interface a true to life PC to the nav display. And for icing on the top, make the touch screen work.

So here is my thinking:
It's my understanding that the Nav system runs a Windows CE OS. This may be wrong, but i'd be willing to bet its not. That said, it stands to reason that the screen would run as a VGA display for the conputer, it may not br 640x480, it may only be 320x200 but it's just as likley that its 800x600. So, it wouldn't be a streach in logic to belive that if one device sends VGA signals too it, then another device could as well, it's more a matter of connection logistics.

Furthermore, it would not be a leap in logic to belive that the touchscreen function of the Nav unit is running as a mouse driver, as many traditional touch screens do (Elo, and the like) so it may be sending back an RS/232 signal or perhaps a PS/2 signal to dicate click coordiantes. I would hope that this, also, could be tapped and fed to the corisponding port on a PC... Or, as coolcat has so boldly suggested, a mac mini... An opinion that I share, as the Mac Mini almost begs to be installed in an automotive environment.

Now, I am a professional computer hacker (the kind that gets paid by companies to keep their networks running) and I come with a long history of hardware hacks and ticks and other such fun. But I certanly lack the knowledge and resources to perform such delicate surgery on the Nav computer in my Ridge...

That being said, I already own just about every conciveable component (even the mac mini) to test and attempt this Frankenstein esk contraption, so if others out there have the knowledge, but lack the resouces, might I suggest that we "put our minds together" as they say...

Please supply your thoughts...
