Celeron 2.4 Ghz P4. 1GB RAM. Windows XP Pro SP2
I have the XM PCR, the D-link USB radio (which is crap and I took it out), Iguidance 3.0 with Itrek gps mouse(not great but not bad either). What I basically use this for is shows. I go there, play some mp3's, play a movie which is typically Pixar's "Cars" since my van is in it as one of the rust-ease guys, and I display the GPS info and map. If there is wireless internet around I'll load something up on the web. Most people are impressed with those basic features. I also have a reverse camera that I may someday install but I can't yet find a good spot for it without making it look stupid.
