This is really nifty. Not sure if you've checked this out yet, but the raspberry pi 7" touch screen fits very nicely in the cubby hole. If I could find a way to cleanly cover up the holes where the hinges go in and out, this would be a great second screen. My head unit also has HDMI input, so might just utilize that but not sure yet if audio will work while viewing HDMI.
*edit* was trying to figure out why that air vent didn't look right - you have a g37 so the above may be useless info
