Abstract

A navigation system includes an improved interface for accessing points of interest. Popular chains and franchises are accessible via a separate search, which can be accessed more efficiently and quickly. The list of popular chains can then be used to access the main database of points of interest.

Claims

1. A navigation system comprising:

a user interface;

a POI database containing points of interest, each record in the POI database having an associated POI name and geographic location;

a chain database, each of a plurality of records in the chain database having an associated chain name, each of the plurality of records in the chain database associated with an associated subset of records in the POI database, and wherein said chain database is pre-loaded in the navigation system prior to an initial access by an end user.

2. The navigation system of claim 1 wherein the plurality of records in the chain database are each associated with a chain.

3. The navigation system of claim 1 wherein each of the plurality of records in the chain database further includes an associated search string that correlates the record in the chain database to the associated subset of records in the POI database.

4. The navigation system of claim 1 wherein the user interface is programmed to permit a user to find a desired record in the chain database and to use the desired record to find a desired associated record in the POI database.

5. The navigation system of claim 4 wherein the user interface is programmed to communicate navigation instructions to a geographic location associated with the desired associated record in the POI database.

6. The navigation system of claim 4 wherein the user interface includes a text entry interface for entering the chain name to choose the desired record from the chain database.

7. The navigation system of claim 6 further including at least one sensor for determining a present position of the navigation system relative to the associated geographic location of the desired associated record in the POI database.
