A navigation system including a drive for reading out navigation data which is stored on a data medium. In addition to the navigation data, a pregap is present on the data medium in which identification data is stored. The drive is designed in such a way that it is able to read CD information in the pregap and compares the identification data stored in the pregap to predefined data to allow or deny access to the navigation data.
