Definition: navigation system


An electronic system in a vehicle or mobile device that provides a real-time map of the current location and step-by-step directions to a requested destination. Often called a "GPS," a navigation system (nav) receives signals from the satellite-based global positioning system (see GPS). See reality view, Google Maps, Waze, CarPlay, Android Auto, in-dash navigation and portable GPS.




The Next Turn
When in destination mode, every nav highlights the next turn. In this example from a Hyundai SUV, the next turn in 1.3 miles (upper right) is the Coastal Highway in the state of Delaware.






An Invaluable Cross-Street Feature
Street signs are sometimes hard to see under normal conditions and often impossible at night. Unless in destination mode where the next turn is displayed, Garmin navigation systems always show the next street ahead in a very large font at the top of the screen. Garmin may have the only navigation systems that display this helpful information in a font easily readable for the driver.
