If you are really serious about getting one of these you could probably get a truck dealer or repair shop to order you one once they are available to the public, but you would still have to fab the mounting hardware. A better option may be to call a Cadillac dealer, that way the hardware would be closer to the application that you have in mind. Either way- Raytheon in Houston is responsible for the actual development of the camera, and the HUD is then developed by Cadillac/Bendix/Chevy (whatever, I don't know who owns who any more), depending on industry.
Good luck-
