BMW Head-Up Display.
The full-colour BMW Head-Up Display projects relevant driving information directly into the driver's line of sight, allowing him or her to fully concentrate on driving. (The display's visibility is reduced when viewed through polarized sunglasses.)
Depending on the car's equipment, along with route guidance this can also include content and warnings from the driver assistance systems.
The symbols, which are projected onto a retractable panel above the instrument cluster, are depicted in full colour so that the traffic signs look realistic. The panel's slightly tinted colour increases the contrast.
The projection's brightness automatically adjusts to outside light conditions, and can also be manually set to reflect individual preferences. The day and night displays also feature different designs. The driver can also select which additional information to display along with the current speed and the warnings from the driver assistance systems.
