Looks like it is just 12v powered and links to your phone, so all the info in screen is generated from an app, not the car. But Looks like they have done a nice job. Biggest issue with these is you then need to use their app for navigation, not in-car.
I want a HUD that shows the car's visualization. Speed, and directions are not that critical to me. Seeing what the car's seeing is what I want. When the car is confused by the painted road lines is what I want to know.
