Mapless GPS navigation system with sortable destinations and zone preference

A method of navigating with a plurality of radially sortable destinations, said method comprising the steps of:

• receiving position information with a GPS receiver and determining a current position thereof;
• storing a plurality of destinations and destination information in a destination data base, each of said destinations being categorized as a predetermined type of destination;
• selecting at least one of said categories from said destination data base;
• means for selecting a location remote from the current position;
• determining a distance from the selected location remote from the current position to each of the destinations within said selected category;
• sorting the destinations of said selected category by increasing radial distance from the selected location to each of the destinations in said selected category;
• arranging said sorted destinations in order of increasing distance so that a user may sequentially select a destination from the arranged sorted destinations;
• and
• displaying the distance from the selected location to a selected destination.
