Embodiment Construction
[0024]Referring firstly to FIG. 1, there is shown a first menu screen 2. of a PND which has been caused by a user to enter a navigation “destination entry” mode. The screen displays a number of icons 4, 6, 8, 10, 12, some of which may be disabled depending on current configuration of the PND, and provide a means whereby a user can navigate simply to a pre-entered “home” destination (4), a list of “favourite” destinations (6), a new address (8), a “recent destination” (10) or a list of many such destinations, and a “Point of Interest” (12) or a list thereof. FIG. 2 shows a second menu screen 14 which results from a user selection of the “address” icon 8. As can be seen in the figure, a further set of icons 16, 18, 20, 22, 24, is displayed, allowing the entry of further information regarding a new destination to which the user desires to navigate. The icons have text labels “City”, “Street and house number”, “Postcode”, “Crossing or Intersection”, and “Spoken Address” respectively, an...

Abstract
A personal navigation device is set out including a display, memory, a processor, a wireless signal receptor and a user input receiver. The memory includes several destination identifiers indicative of a number of recently visited destinations. A database is also included, the database itself including digitized map data and descriptive data identifying features represented within the digitized map data. The personal navigation device also includes software capable of performing navigation between a current location determined from the wireless signals received and a destination at least partially identified by said user input. The software further includes a facility for displaying one or more categories of destination which when selected causes the display of one or more destination identifiers of the recently visited destinations of that category in list format, and for performing a search within the descriptive data representative of the particular destination category in response to the user input.
