now i could be wrong about this... but the only way i could think to do it without a a carputer... would be to use a double din or flip out screen for your main unit and run a video out to a dedicated touch screen monitor... only thing i don't know would be whether the main source unit would recognize the signal from the touch screen back to the original unit since its an out from the main unit to the touch screen... unless you could run a loop... video out from main to touch screen... and then out from touch screen to in on the source... but i think that would be too conflicting to work.but i dont need a computer in my car. Why over kill it for nothing.
either way if you find something let everyone know... im curious myself
