I think what you are thinking of is a carputer. It is a computer permanently built into your car, with usually a touchscreen where the radio is. www.mp3car.com is a great website for this stuff.

There is one installed in a Monte.

 

Or you can do what i did:



that setup was with my other laptop. thestand made the carlook too much like apopo. couldnt get anyraces out of people lol. again it wasnt a perminate spot for the laptop cause i would be just inviting someone to break in and steal it. now ihave a slightly smallerlaptop that i use.

i have thelaptop mainly there for when im tuning the car. but i also have a cable to connect my GPS and use Nav software, obviously it has DVDand i can input the sound into the car. looked pretty trick for that car show (last pick)

 

Mine is connected for entertainment. It has a DVD and WIFI in it, but could be for navigation. It can connect to the Pioneer deck up front or thru RCA jacks in the back for tailgating. I also have 110v both in front and back to run the laptop.
