Here is a Link to what a heads up display on a lexus series car looks like. the HUD is available as an option on many of their models

Heads Up Display - 2013 Lexus GS 350 Long-Term Road Test

I also have a V1 that I have been happy with for many years.

I want to display the output from the V1 to the HUD. I couldn't find an SDK (Software Devlepment Kit) for work with the HUD. I think this would be very cool. It's the ultimate in concealment.
