Abstract
A navigation system that enables a user to search for points of interest across categories is provided. The user may enter a character string of a desired destination into the navigation system using a user input device. The navigation system will search for points of interest in the database for the character string. The character string may be from the first portion of the name of the point of interest or somewhere in the middle of the name of the point of interest. In this manner, the user will be able to locate a point of interest from the database while having a partially incorrect name. Additionally, the navigation system may relate the points of interest to the vehicle location, such as by vehicle direction or proximity of the points of interest to the vehicle.
