Abstract
A navigation system stores navigation data in an access-protected manner. The navigation system includes navigation units that utilize the navigation data retained in a memory. The system includes a module for authenticating the access code. The system may include a module for generating an access protection code for storing the navigation data in memory. The access code and the access protection code may be used in a complementary scheme to secure the navigation data set.
