everyone is correct. i've seen several installs done w/ computers in car mags. alot of it was for mp3 playing (unless your a computer engineer and your going to do custom programming to run stuff in your car). pretty much all the basic advantages of a car computer are now handled by aftermarket car audio manufacturers. i have the link for a car specific computer that some manufacturer offers. if your truly serious, i can try to dig it up and scan the articles w/ the installs to give u an idea. pls only if your serious. lemme know. send me a pm or something.
