Car navigation refers to systems that help drivers find their way while traveling. These systems use GPS technology to determine the vehicle's location and provide directions to a desired destination. They can offer real-time traffic updates, estimated arrival times, and alternative routes to avoid delays. Modern car navigation can be found in built-in infotainment systems or as standalone GPS devices. Many drivers also use navigation apps on their smartphones, which can provide voice-guided directions and additional features like points of interest. Overall, car navigation enhances the driving experience by making travel more efficient and less stressful.
