In-car navigation systems are electronic devices or software applications that help drivers find their way while on the road. They use GPS technology to determine the vehicle's location and provide real-time directions to a chosen destination. These systems often include features like traffic updates, estimated arrival times, and points of interest, making it easier for drivers to plan their routes. Many modern vehicles come equipped with built-in navigation systems, while others can use smartphones with navigation apps like Google Maps or Waze. These systems enhance driving safety by allowing drivers to focus on the road while receiving audio and visual guidance for navigation.
