Yes, I have a real live computer in my car. I haven't got around to rewriting my page on it yet, but in the meantime you can read my old page about it. It's a tad out of date, but most of it is still valid.
Over this summer (2005) I'm planning on writing my own GPS and multimedia software for it. I'd like to migrate the system to Linux, as my car PC is the only Windows machine I have left now...
Also see mp3car.com, it's an excellent resource.
Details to follow at some point.
