built in sat nav

**Built-in sat nav** (short for *built-in satellite navigation*) refers to a **navigation system that is permanently installed in a vehicle by the manufacturer**.

It uses **GPS (Global Positioning System)** technology to provide directions, maps, and route guidance directly through the car’s integrated display screen and audio system.

Unlike portable GPS devices or smartphone navigation apps, a built-in sat nav is:
- Part of the vehicle’s dashboard system
- Controlled through the car’s touchscreen, buttons, or voice commands
- Powered by the vehicle itself

It typically includes features such as real-time directions, traffic updates, points of interest, and route planning.
