Abstract
A system and method are disclosed for conducting searches and generating routes to selected points of interest using a wireless client-server (WCS) navigator. A method includes the step of requesting, at a mobile unit, information about one or more locations meeting certain criteria. Locations meeting the criteria are displayed on the display screen at the location of the user and, if a location is selected, a route to include the selected location is automatically generated. Guidance regarding how to travel to the selected location may also be provided. If the user is already en route to a destination when a route to a selected location is requested, the navigator may generate a route that includes both the original destination and the selected new location. If the user is already en route to a destination when locations matching criteria are requested, along with the locations displayed the navigator may provide information to the user as to the total travel time or distance of a route passing through the original destination and a new location or the additional travel time or distance in comparison to the original route. The method may further include the step of requesting information about a class of locations such as restaurants.
