1. A method for displaying visual information in a navigation system comprising:
- identifying a geographic region for display in a map;
identifying a first plurality of map features that are located in the identified geographic region from a database storing a second plurality of map features in association with predetermined priority levels for each map feature in the second plurality of map features;
identifying a portion of the first plurality of map features with associated priority levels that are below a first predetermined threshold;
modifying graphics data associated with each map feature in the portion of the first plurality of map features to generate graphics data with a reduced level of detail for each map feature in the portion of the first plurality of map features; and
generating a first display of the map for the geographic region with a display device, the first display of the map including a visual depiction for the first plurality of map features with the first display being generated using the modified graphics data for the identified portion of the first plurality of map features.

Abstract
A method for displaying visual information in a navigation system includes displaying a map of a geographic region including a first plurality of map features where each map feature in the first plurality of map features having an associated priority level that is below a predetermined priority level is displayed with a reduced level of detail. The method further includes identifying a second threshold in response to receiving an input signal from an input device and generating a second display of the map, the second display of the map including a modified visual depiction for at least one map feature in the first plurality of map features.

14. A navigation system comprising:
-
a display device configured to generate a display of a map; an input device configured to receive input corresponding to a selected threshold for display of map features in the map; a memory configured to store a database including geographic data, a plurality of map features, graphics data associated with each of the plurality of map features, and each map feature in the plurality of map features being associated with a priority level in the database; and a processor operatively connected to the display, the input device, and the memory, the processor being configured to; identify a geographic region for display in a map; identify a first plurality of map features that are located in the identified geographic region from the database; identify a portion of the first plurality of map features with associated priority levels that are below a first predetermined threshold; modify graphics data associated with each map feature in the portion of the first plurality of map features to generate graphics data with a reduced level of detail for each map feature in the portion of the first plurality of map features; and generate a first display of the map for the geographic region with the display device, the first display of the map including a visual depiction for the first plurality of map features with the first display being generated using the modified graphics data for the identified portion of the first plurality of map features. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
