I have sort of a weird set up in my 97 dodge ram. I have a pentium 100 desktop system under my seat and a laptop behind the seat. I ran a null modem cable from the desktop system to the laptop and am using PC Anywhere to control the desktop system from the laptop. This way I can just have a slow laptop with a small drive and have still have a huge drive for MP3s. I made an extended ribbon cable for the laptop display and made a mount so I could hang it on the dash. It works "ok". It does get the job done, but it isn't what I want. So to answer your question, you can extend the display, but it is a pain to make it.
