Car navigation systems are electronic devices that help drivers find their way while traveling. They use GPS technology to determine the vehicle's location and provide directions to a desired destination. These systems can display maps, suggest routes, and offer real-time traffic updates, making it easier for drivers to navigate unfamiliar areas. Many modern cars come equipped with built-in navigation systems, but there are also portable options and smartphone apps available. Popular applications like Google Maps and Waze provide additional features, such as user-generated traffic reports and alternative route suggestions, enhancing the overall driving experience.
