ooo, how'd you do that? I've been wanting to mod my steering controls to do that forever...
(I just gave up and bought a touchscreeen)

That's so very cool. How much would it run to set something like that up? I really think my truck needs a computer.
These are really rough estimates...
PC Parts: ~$500 (Power supply and SSD is most of this cost)
7" Touchscreen: $180 ($450 for a transflective one, I may go this route later)
Tools: I already had them
Parts to modify a dashboard: $20-150 depending on car
Aux input (or replacement head unit): $80-100
Misc other stuff like wiring, wood, bondo, etc: $100
Software: Largely varies. (LinuxICE: free; Windows + Centrafuse + Nav: A lot more than free)
So I guess like $1000ish total. I didn't count in any of the speaker upgrades or stuff like that because it's mostly unnecessary. A lot can be cut back as well if you already have PC parts, don't care about really fast boot times, have an easy dash to put a screen in, etc. If you consider that a car's nav system tacks $2000 on to the price I don't think it's so bad.
