A navigation system is a device or group of devices designed to help people navigate from one place to another. It can include GPS technology, maps and other tools that provide directions, locate points of interest, and display travel routes. Navigation systems are commonly used in vehicles, but they can also be found on smartphones, tablets, and other portable devices. The goal is to make it easier for people to find their way from one location to another by providing accurate and up-to-date information about the surrounding area.
