Well I found out that the NAV system is OEM from Alpine. I will call them on Monday and see if I can find out what the resolution is.

Worst case, I will move the NAV/CD/Radio down a few inches in a custom built housing and have the bigger screen up top for hte computer, probably this one from Xenarc: http://xenarc.com/product/700ts.html

I will absolutely, positively not use Windows. I am a professional Mac guy. I can do everything I need to do with Mac OS X. I already have the G4 Cube in my office and I am ordering all the components I need (USB mic, fingerprint authentication, USB hubs, etc.) I've contacted a few custom audio shops to see who can assist with making everything look professional once installed (mainly power and positioning of components without making the dash look like Baghdad when everything is done.
