Title: Navigation system with feature for reporting errors

Abstract: A feature whereby an end user of a navigation system that uses geographic data can easily report perceived errors or inaccuracies in the geographic data or other problems such as poor quality route calculation or guidance. The end user uses a user interface of the navigation system to indicate the perceived error, inaccuracy, or other problem. The navigation system includes a report program that operates in response to the end user's indication. The report program collects information indicating the error, inaccuracy, or other problem and sends a report including the collected information to a geographic database developer. The geographic database developer can use the information in the report to update a geographic database.
