yaris lcd and computer set up

My Yaris 07 has a small radio slot maybe 3" high by standard width. I would ,if practical, like to install a portable pc and lcd that controlled all comm. fm,gps,cell antenna with amp and 2.4g with antenna and amp. Looking for ideas and pictures to see if its worth undertaking. Need to find dual purpose antennas and not have interference issues. would like to keep it to 2 antennas,low profile mounted on the 2 back corners of the roof.I want the computer to be fully func. with XP.Ideas?? thanks.

some company on ebay has din sized full computers that just need a monitor to hook up to and a keyboard/mouse (might have remote, but dont know) with XP already on them"If a man made it, another can modify it...it just takes some thinking."
