The invention relates to a method of producing a multifunctional functional unit with a rigid support structure, in which control elements and/or display elements are arranged behind a transparent surface layer which is continuous over substantially the entire functional unit. The method includes punching a positioning hole in a transparent plastic film with a thickness in the range of 0.1-0.4 mm; positioning the film into an injection mold using the positioning hole, with a corresponding positioning means for engaging in the positioning hole; back-injecting film to form a plastics support on the first side, the injection mold being designed such that, of the plastic film is not back-injected at the control elements and/or display elements, on the second side the plastics film is flooded with a transparent curing casting compound to form a continuous transparent surface layer.
