Abstract: A method of creating a customizable exercise route for a user of a personal navigation device is disclosed. The method includes providing routing instructions for a user along a first route, recording a first speed for a user traveling between a first point and a second point on the first route, providing routing instructions for a user along a second route, recording a second speed for a user traveling between a third point and a fourth point on the second route, comparing the first speed and the second speed to calculate a performance difference related to the first route and the second route, and notifying the user about the performance difference.

Abstract: In a method of transmitting a traffic event report for a traffic event from a personal navigation device, positioning circuits determine position of the personal navigation device. Processing circuits calculate speed of the personal navigation device according to the position, determine a street the personal navigation device is traveling on according to the position, calculate difference of a speed limit of the street and the speed of the personal navigation device, and display a traffic event report dialog in the display upon detection of the difference being greater than a predetermined threshold. An input interface receives traffic event data through user input, and the networking circuits send the traffic event report including the traffic event data to the server.
