  "textContent": "The device has a position determining unit that determines a position (401) of a vehicle. A map database stores map data representing road segments (203) and having identification elements, such that each segment is associated with identification features. A reference database stores identification features and velocity information. An arithmetic unit determines an identifier in the segments, for reading identification feature with velocity information and obtaining a velocity value from the speed information. An output unit outputs the speed value to a user. An independent claim is included for a method of operating a navigation device.",
