Bobby_X,
Thanks and to answer your questions:
1. My Xterra is an XE model so it didnt have an overhead light where the monitor went. I had to cut a hole.
2. If you check my original link, I added some closeups of the text for you.
3. I know that 7" wide touchscreen overlays are available although I dont know pricing for such.
I got a lot of my ideas for the XPuter from the site
www.mp3car.com You might check it out.
