crazybusgroup, take a look [http://www.mp3car.com/show-off-your-project/137893-apple-tv-installed-a-1999-sc400.html|on here] and read through [http://www.appletvhacks.net/2007/10/05/apple-tv-as-an-in-car-entertainment-system/|this forum] It should tell you all you need to know to get started. Especially the last link, since it does have a list of parts needed. Best side for those modes is mp3car.com. Hope this helps, good luck and let us know how it is going.
