In the superdutys its even easier!!!!
Here is where a Jcain used a Nexus 7 in place of the factory stereo... The buttons on the Ford stereos is just a little panel that you unplug in the F250 the factory stereo can stay in place.. super easy... Nexus 7 fits like a dream press fit.. Just make a home screen and some cool backgrounds and done


There is an app called Tasker to make it all work...
If you have just a little ability to make things work you could do your superduty with the nexus 7 in an afternoon..
The 9" tablet in my truck is a little more involved. Plastic welding. Bondo sanding paint clear coating.. flipping factory stereo up and some small cuts behind the dash bezel
