A method controls an Internet portal for a social network service from a motor vehicle. The Internet portal provides functions that can be activated by sending a control command to the Internet portal. An immobile proxy device provides a module that receives a selection, which is made by a user in the motor vehicle, for one of the functions and then sends a control command, which is specific to the Internet portal, for activating the function to the Internet portal. The module also produces suitable display data for the motor vehicle from output data from the Internet portal. The module also receives additional data from an additional data source and produces an additional control command for the Internet portal and/or display data for the motor vehicle therefrom.
