A method for displaying data on a motor vehicle display apparatus comprising the following steps:

• receiving the data and a signature of the data by a first interface,
• checking validity of the signature by using a first certificate stored in a second memory area,
• storing the data in a first memory area, if the signature is valid,
• storing a motor vehicle identifier in a third memory, wherein the motor vehicle identifier identifies a motor vehicle unambiguously, to which the motor vehicle display apparatus is assigned, wherein the third memory area is a protected memory area, wherein the first interface is adapted to receive a message, wherein the message comprises at least the data, identifying information and the signature of the data and/or of the identifying information, and is capable of checking if the identifying information matches the motor vehicle identifier stored in the third memory area, wherein a condition for storing the data in the first memory is that the identifying information and the motor vehicle identifier match each other,
• actuating a display apparatus for displaying the data.
