Abstract: A method operates an infotainment system in order to provide an overview of audio data records detected by a music output device. An evaluation device arranges the detected audio data records into an audio data record group according to a selection criterion, e.g. the artist. The evaluation device determines a value of a predetermined user-relevant evaluation variable for each audio data record. On the basis of the respective values, the evaluation device then determines a ranking list of the audio data records in each audio data record group. The evaluation device generates a digital image for each audio data record and assigns the images of those audio data records that are combined into an audio data record group to an image group. The position of the images in an image group depends on the position of the respective associated audio data record in the ranking list.

Abstract: A motor vehicle has an infotainment system with a controller for providing infotainment functions and a display unit, which is structurally separate from the controller and which has a screen for displaying display data. The display unit is retained in a motor-vehicle interior by a retaining device. The display unit allows a suitable posture when viewing different infotainment functions on the display unit by making the retaining device and the display unit nondestructively and reversibly detachable from each other. The controller is designed to transfer the display data to the display unit even while the display unit is detached from the retaining device.

Abstract: A device for projecting image data in a motor vehicle includes a projection surface secured to a roof inside the vehicle and a projector secured at the rear behind the passengers watching the projection.

Abstract: A projection system for optical reproduction of information or entertainment data for employment in the area of passenger transport (airplane, automobile area). Therein a laser projector is used for generating an image line by line upon surfaces within the vehicle internal space. By rotation or pivoting of the laser projector or displacement along a guide rail practically all surfaces in the internal space of the vehicle can be reached.
