Navigation system definition and meaning

A navigation system in a car helps the driver get from one place to another. It can be used to find the shortest route to a destination or to avoid traffic jams. Navigation systems usually have a map of the area that they cover, and they can be updated with new information about roads and landmarks. Some navigation systems can also provide turn-by-turn directions, and some even have features like real-time traffic updates. Navigation systems can make driving much easier, and they are becoming more common in cars today. Many new cars come with built-in navigation systems, and there are also many aftermarket options available.
