1. A method for synchronizing in a motor vehicle, comprising: detecting, using an optical sensor device and 3D image data, an operating gesture of a user which comprises a movement of a body part of the user, carried out freely in a space; generating a gesture signal describing the operating gesture and transmitting the gesture signal to a gesture detection device; identifying the operating gesture at the gesture detection device; identifying an origin display device of the motor vehicle and a target display device of the motor vehicle, the origin display device and the target display device being identified at the gesture detection device using the gesture signal; identifying a first origin data record selected by the operating gesture, the first origin data record being identified at the gesture detection device, the first origin data record being one of a plurality of origin data records simultaneously displayed by the origin display device, the first origin data record comprising a first display content relating to a first predetermined thematic context; receiving a control signal at a control device, the control signal being received from the gesture detection device, the control signal describing the first origin data record; determining the first predetermined thematic context of the first origin data record based on the control signal, the first predetermined thematic context being determined at the control device; determining a further data record based on the first predetermined thematic context, the further data record having a second display content for the first predetermined thematic context; and displaying the further data record on the target display device so as to synchronize the origin display device and the target display device, wherein a second origin data record among the plurality of origin data records comprises a third display content relating to a second predetermined thematic context, the first predetermined thematic context is common to the first origin data record and the further data record and includes information on a first vehicle system relating to operation of the motor vehicle, and the second predetermined thematic context is common to the second origin data record and another data record having a fourth display content for the second predetermined thematic context, and includes information on a second vehicle system relating to operation of the motor vehicle.
