He does have his moments that's for sure. I reckon I've seen him a bit too much now though.
Back on topic - I had an idea. This is all theory so feel free to tell me if this will not work:
If I identify the RGB (and sync) cables going into the factory screen then I should be able to wire those into a new screen.
If I can do this, then I just need to add a switchbox which allows me to select the factory input or the car pc. In car pc mode I will be able to use the touchscreen as normal.
This does require the RGB signal to be standard but I don't think they would make something bespoke just to be difficult do you?
All opinions appreciated
