METHOD FOR PROVIDING A SIGNAL OUTPUT ON THE BASIS OF A MAIN FILE AND A PLURALITY OF SECONDARY FILES, AND MOTOR VEHICLE

摘要

In order to provide additional functionalities in an infotainment system of a motor vehicle, a method for providing a signal output, in which a main file is transmitted that refers to secondary files and indicates an identifier related to each secondary file. The identifier can be calculated upon receipt of the main file (for example in the motor vehicle) for a secondary file already provided in the motor vehicle and compared with the identifier contained in the main file. Thus, the secondary file does not need to be downloaded every time, but can be provided in a buffer memory. The identifier shows if the secondary file provided is the most recent version thereof.
