If you're putting something like that in, get an alarm. I have a friend with an accord and he has a screen in the center console, with a full computer in the trunk. The screen also uses the stereo spot, since it can be used to play music as well. You can get good touch screens for that, or put a small keyboard in the glove box. Make sure to have a cover plate for it if you do it, again, it's something to get stolen.
