First Claim
1. A method for displaying information and operating a mobile device not assigned to a motor vehicle via an electronic unit in a motor vehicle, the motor vehicle electronic unit having a display and an operating device of a motor vehicle, the method comprising:
- storing, on the mobile device, a program executable on the mobile device, wherein the program comprises user interface program parts to provide a user interface for operating processes of the program, the user interface having fixed areas for displaying variable contents;
storing, on the mobile device, a digital certificate, which is assigned to the user interface program parts;
transmitting the user interface program parts, with the at least one certificate assigned to the program parts, from the mobile device to the electronic unit of the motor vehicle;
receiving and storing the user interface program parts and the at least one certificate assigned to the program parts at the motor vehicle electronic unit;
transmitting program data to the motor vehicle electronic unit from a vehicle bus and the mobile device;
receiving and storing the program data at the motor vehicle electronic unit, wherein the user interface program parts in the motor vehicle electronic unit receive and process the program data received from the vehicle bus;
verifying the user interface program parts received and stored in the motor vehicle electronic unit based on verification of validity of the transmitted at least one digital certificate in the motor vehicle electronic unit;
establishing access to the program data by the user interface program parts in response to verification of the user interface program parts in the motor vehicle electronic unit;
executing the user interface program parts transmitted from the mobile device in the motor vehicle electronic unit in response to verification of the user interface program parts in the motor vehicle electronic unit; and
displaying, on the motor vehicle electronic unit display, the variable contents in the fixed areas of the user interface for operating processes of the program executable on the mobile device.

Abstract
A method for operating a mobile device, not assigned to a motor vehicle, via an electronic device with a display and operator control device of the motor vehicle is made available. The program has program parts for a user interface and for operator control sequences which are assigned a digital certificate. The user interface comprises fixed areas for displaying variable contents. The program parts are transmitted together with the digital certificate to the electronic device of the motor vehicle and are carried out when the certificate is successfully checked. The transmission of data without protection by a digital certificate is restricted to the variable contents for display in the fixed areas of the user interface.
