1. A method, comprising:
- obtaining information indicative of a current position and a desired position; and
navigating between said current position and said desired position by first mapping a portion of the route closest to the current position, but less than the entire portion of the route, beginning a guiding operation which guides a user of the system along the route, and subsequently finishing said mapping by mapping the remainder of the entire portion of the route.

Abstract
A system for improving the operation of a GPS based navigator. Statistical and/or time of day information is used to select the best route between a current location and a desired location. The statistical information may take into account anomalies, and a user can select the amount of risk they which take. The system can be updated with more updated information. In addition, the selection of the desired location can be carried out by downloading information from a PDA.

10. A system, comprising:
-
a memory, storing map information; and
storing roadway conditions indicative of actual times to traverse different sections of roadway;
a user interface, allowing entry of a destination for navigation;
a processor, computing a path to said destination, based on said map information, by selecting a path based on said roadway conditions; and
an update element which allows updating said roadway conditions to define new and more recent times to traverse said different sections of roadway. - View Dependent Claims (11, 12, 13, 14)

16. A system, comprising:
-
a memory, storing map information, including commonly requested destinations by each of a plurality of users;
a user interface, allowing entry of a destination for navigation including allowing selection of one of said most commonly requested destinations;
a processor, computing a path to said destination, based on said map information, by selecting a path. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A system, comprising:
-
a position determining element, which operates to automatically determine its position;
a memory, storing map information;
a user interface, allowing entry of information for mapping, and displaying information from at least one of said map information and said position;
a processor, computing information based on said information for mapping, and also using said position information from said position determining element to determine a speed of movement, and wherein said processor compares said speed with a target speed and provides an indication when said speed exceeds said target speed by a specified amount. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A system, comprising:
-
a position determining element, which operates to automatically determine its position;
a memory, storing map information;
a user interface, allowing entry of information for mapping, and displaying information from at least one of said map information and said position;
a processor, computing information based on said information for mapping, and also determining a likelihood that the position detecting by said position detecting element is correct, and wherein said user interface displays information indicating said likelihood. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43)
