Abstract: A method of operation of a navigation system includes: receiving a navigation external data including a vendor data, a delta data, or a combination thereof; generating a normalization data with a control unit based on transforming the navigation external data according to universal format; generating an aggregation changeset data by splitting the normalization data into each instance of a dimension type; and updating a navigation local data by applying the aggregation changeset data according to a layer prioritization for presenting the navigation local data on a device.

Abstract: A method is provided for operating a navigation system of a motor vehicle for searching for possible destinations, wherein a processing device of the navigation system is used: to receive a search input from a user, to search a first database and a second database for suitable database entries in each case on the basis of the search input and in this case to provide a first and a second results list of suitable database entries. The first database stores database entries that indicate geographical regions, and the second database stores database entries that indicate road names and/or special destinations. For each road name and/or special destination the second database indicates a reference to at least one geographical region. The processing devices determine entry pairs that each contain a database entry from the first results list and a database entry from the second results list as the possible destinations.
