Interested in this too.
If you can get the thing small enough, throw it in a JDM edgeless rear view mirror and run an LCD display behind it, display the info on it like smartmirrors.
Heck even if the unit itself was a box somewhere under the dash, you could run a wire to the rear view mirror for the LCD and possibly some touch sensors for input.
And a random mockup of what i'm imagining.
