62 30... Notes on head-up display

NOTE: A special windscreen must be fitted to ensure that the Head-Up Display illustration can be projected correctly.
This windscreen comprises three sections. An outer and an inner glass pane are connected by a wedge-shaped plastic film.
The wedge shape prevents double projection of the Head-Up Display.
When the windscreen is replaced, the vehicle identification number and BMW parts catalogue must be checked to ascertain whether the windscreen in question is suitable for HUD. 

Example of the display with a conventional windscreen: 

With a conventional windscreen, the projected illustration is reflected on the inner and outer glass pane, producing a double illustration.
