Well after a few more weeks of lurking on the forum, I decided to change my proposed setup. I got a great deal on a galaxy tab 2 so I've decided to put that in instead of a mac mini. The biggest issue I'm going to have is fitting the galaxy tab in the space where the factory nav unit is currently (the tab is too tall in landscape mode and too short on the sides). I'm going to have to learn how to fabricate in order to get the perfect fit. I picked up the JBL harness and it works great so the audio is taken care of. As far as power, I have an AC plug in the truck so I can just plug it into that to charge it, I can also get the vehicle adapter to the cig lighter and plug it into that for now. I've seen that people are using the tasked app, which will help for automation. I'm going out of town for a while so I'm going to have a temporary set up where it's just connected to the dash with a car mount.
