What is a Sat Nav?
A sat nav, short for satellite navigation system, is a GPS-powered device that provides real-time directions, maps, and traffic updates to help drivers navigate from point A to B efficiently. Unlike smartphone apps, dedicated sat navs offer larger screens, voice-guided navigation, offline maps, and features like speed limit alerts and lane guidance. Popular with road trippers and commuters, sat navs help reduce travel time, avoid traffic, and improve route accuracy—especially in areas with poor mobile signal.
