So I didn't have any luck with trying to make a design in CAD easily. Right now I'm in the middle of installing a Sony XSP-N1BT. I've wanted an android head unit and while the App Radio is a nice set up it requires a lot of wiring and cost almost 3 times as much. Here's a picture of what it looks like right now. I'll be adding plexiglass to fill all the open spots and then I'll take measurements for a CAD design.
