A method, comprising: providing a map database; providing a landmark database; providing at least one user-specific landmark type corresponding to a business of a specific brand or chain; determining navigation instructions based on the map database, the landmark database, and the at least one user-specific landmark type; outputting the determined navigation instructions to the user to guide the user to a desired destination, wherein, when at least one user-specific landmark type is usable, it is used for navigation instructions; when receiving an input from a user regarding the desired destination, a route is calculated based on information in the map database and corresponding navigation instructions are output, which are generally given at or near specific locations where a navigation instruction is needed, identifying at least one landmark in a vicinity of a location needing a navigation instruction, checking if the at least one identified landmark matches a landmark type of the at least one user-specific landmark type, and, if yes, determining the navigation instructions includes determining the navigation instructions such that they include a reference to this landmark of a user-specific landmark type, after a current address or coordinates of the navigation system is retrieved or the destination input from a user is received it is checked if at such determined or input address a point of interest or other landmark exists, and if a POI or other landmark exists at the address, it is checked if the POI or other landmark matches with an existing user-specific landmark type, characterised in that: - if this is not the case, a landmark type is created with a score of 1, - if a user-specific landmark type exists already, the score of this landmark type is increased by 1, if the score after increasing exceeds a predetermined threshold, the landmark type is added to the user-specific landmark types usable for outputting navigation instructions referring to the landmark type decreasing the score, if a specific landmark type has not been visited for a predetermined time period. providing a map database; providing a landmark database; providing at least one user-specific landmark type corresponding to a business of a specific brand or chain; determining navigation instructions based on the map database, the landmark database, and the at least one user-specific landmark type; outputting the determined navigation instructions to the user to guide the user to a desired destination, wherein, when at least one user-specific landmark type is usable, it is used for navigation instructions; when receiving an input from a user regarding the desired destination, a route is calculated based on information in the map database and corresponding navigation instructions are output, which are generally given at or near specific locations where a navigation instruction is needed, identifying at least one landmark in a vicinity of a location needing a navigation instruction, checking if the at least one identified landmark matches a landmark type of the at least one user-specific landmark type, and, if yes, determining the navigation instructions includes determining the navigation instructions such that they include a reference to this landmark of a user-specific landmark type, after a current address or coordinates of the navigation system is retrieved or the destination input from a user is received it is checked if at such determined or input address a point of interest or other landmark exists, and if a POI or other landmark exists at the address, it is checked if the POI or other landmark matches with an existing user-specific landmark type, characterised in that: - if this is not the case, a landmark type is created with a score of 1, - if a user-specific landmark type exists already, the - if this is not the case, a landmark type is created with a score of 1, - if a user-specific landmark type exists already, the score of this landmark type is increased by 1, if the score after increasing exceeds a predetermined threshold, the landmark type is added to the user-specific landmark types usable for outputting navigation instructions referring to the landmark type
