Patent ID: 8554471

Claim:
A method, comprising: continuously determining a current speed using information received from satellites by a global positioning system (GPS) receiver in a navigation device during travel along a road, and outputting, on a color display of said navigation device, a numerical value of the current speed and a permitted speed for the road, an indication of a relationship between the permitted speed and the current speed and map information including a representation of said road, said navigation device determining whether a speeding condition exists for a selected duration of time by continuously comparing said current speed with a permitted speed for said road, the permitted speed being stored in a memory of said navigation device, and, if a speeding condition is determined to exist for more than the selected duration of time, highlighting the indication of the relationship between the permitted speed for the road and the current speed by changing an output color of the indication of the relationship between the permitted speed for the road and the current speed on the color display of the navigation device to one of a plurality of colors and /or flashing the indication of the relationship between the permitted speed for the road and the current speed until such time as the speeding condition no longer exists.
