At first I was thinking to do something fun in my car with the RaspberyPi like this guy:
Thoughts on in car computer?
Then I found this:
Android Mini PC
Which I could hook up to this:
SAMSUNG Resistive Touchscreen or this:
With Bezel
This touchscreen would also complement a back-up camera since it has the trigger to automatically switch to the back-up camera video feed.
If you want, you can also add a powered hub and attach things like GPS or a hard drive for your full media library.
I plan on doing this in the future but do not quite have the funds to do so. Just some random thoughts and ideas I thought might be useful to someone looking to replace that dreaded compartment in the middle.
