Abstract (en)
[origin: WO2005083701A1] The invention relates to a navigation system provided with a drive for reading data stored on a data carrier which, in addition to navigation data (3), comprises a pregap storing identification information. The inventive drive is configured in such a way that it reads CD-information in the pregap (2) and enables or refuses an access to navigation data (3) by comparing identification data stored in the pregap (2) with specifications.
