We've contacted LG-Phillips a few weeks ago to try to get a test version of this unit fitted as a touch screen with a VGA compatible input.
They responded initially and advised us that they would have to modify the unit for touchscreen operation. LG does produce these for others as a OEM, but does not sell one themselves. I'm guessing that Mirco/Ford will lock up the entire output; but that's just a wild guess. I'm hoping to be able to test something soon.
This link provides their a small glimpse of ther future thinking.
