How long should the navigation RST button be pressed to restore factory settings?

Press the navigation RST button for about 10 seconds to restore factory settings. Below is relevant information about car navigation systems: 1. Concept: A car navigation device is a driving assistance tool that helps users accurately determine their current location, calculates routes based on set destinations, and guides users to their destinations through map displays and voice prompts. 2. Operating Principle: GPS consists of three main components: space satellites, ground monitoring, and user receivers. In space, 24 satellites form a distributed network, positioned in 6 quasi-synchronous orbits around the Earth, each orbit 20,000 kilometers above the ground with an inclination angle of 55°. Each orbit contains 4 satellites. GPS satellites orbit the Earth every 12 hours, enabling any location on Earth to simultaneously receive signals from 7 to 9 satellites.
I often encounter situations where the navigation system malfunctions and needs a reset. Based on my experience, to restore factory settings, you need to press and hold that RST button for about 5 to 10 seconds. The exact duration may vary depending on the car model—for example, some Japanese cars only require 5 seconds, while some European models need a longer press. Sometimes the screen will flash to prompt you to release the button. Why do this? Because it clears all stored data and error settings, solving common issues like system lag or inaccurate positioning. However, be careful—after the reset, all customized settings will be lost, including navigation history and preferences, so you'll need to reconfigure them. I recommend checking the owner's manual for the precise timing before proceeding or parking the car in a safe place to test it, to avoid any mid-drive mishaps that could affect driving safety.
