To provide a simple interface that can operate seamlessly across a mix of databases with different categorization, individually or concurrently, and limit categories offered to those categories directly relevant to a search term entered, a method of querying and displaying point of interest category and point of interest item information in a personal navigation device includes sending a search term to a first server, receiving matching category data from the first server, displaying a representation of the matching category, sending a query to a second server when the matching category is selected, receiving point of interest data corresponding to the matching category from the second server, and displaying a point of interest described in the point of interest data.
