I just had the itch to put a computer in my dd. My rough plan is to use an old dell lappy with a borked screen. What I want to do is mount the lappy with or w/o the screen under the pass seat then hard wire a power inverter. I would also run a usb cable up through the center console to plug my cell phone in so I can use it as a modem. (I have unlimited data on my cell plan) I would then need source a touch screen of some kind and mount to the dash or find a factory nav unit to hack up. I would like to keep the factory head unit though. I can run the lappy audio to the aux input of the stock unit for MP3's, movies, and what not. I am sure I am missing something. I need to start on a wiring diagram. I just think it would be cool to have internet access at all times while driving, not just when you can find a wireless connection to steal from. If anyone has experience with something like this please feel free to tell me how stupid the idea is.
