Abstract

A method for operating a navigational system having a digital map base which is a reproduction of real geographical regions and contains data on geographical elements, as well as a device which retrieves and processes data, such as an operating device having a display unit. In this context, a data directory of the data present in the digital map base is transmitted to the device which retrieves and processes data, and the device which retrieves and processes data selects data, to be requisitioned from the digital map base using this data directory.
