GMC has offered a bit of insight into the seemingly simple heads up display some of its vehicles such as the 2012 Acadia SUV uses. The heads up display in the car is designed to allow the driver to keep your eyes on the road and still see important details such as what year you're in, the speed, and RPMs of the vehicle. This is similar to the tech fighter pilot used to keep your eyes ahead at all times.
The technology will also indicate other things in the GMC vehicles such as vehicle warnings, outside temperature, turn signal activation, and radio information. The driver can adjust the position on the windshield, the display can be dimmed or brightened, and can be turned off. GMC says that the HUD was designed as part of the instrument panel.
The GMC system uses a series of mirrors and a display screen to project the HUD on the windshield.
