How to Upgrade the Navigation System in a Car?
2 Answers
It is best to visit a 4S shop for after-sales service or go to an auto repair shop for the upgrade. Below is some relevant information about car navigation systems: 1. Concept: A car navigation system is a driving assistance device that helps users accurately locate their current position and calculates the route based on a set destination, guiding users to their destination through map display and voice prompts. 2. Operating Principle: GPS consists of three main parts: space satellites, ground monitoring, and user receivers. In space, 24 satellites form a distributed network, each located in one of six quasi-synchronous orbits around the Earth, 20,000 kilometers above the ground with an inclination angle of 55°. Each orbit has four satellites. GPS satellites orbit the Earth every 12 hours, allowing any location on Earth to simultaneously receive signals from 7 to 9 satellites.
I often think about how to make the car navigation system more practical. The upgrade method depends on the system type. If it's a built-in factory navigation system, like those in Toyota or Volkswagen cars, I first check the manufacturer's official website for the support page and download the latest map package to a USB drive. Then, I start the car engine, plug the USB into the interface, and follow the on-screen instructions step by step to install it. Don't rush during the whole process, as a power failure might interrupt the update. Why is upgrading important? Outdated maps can easily lead to wrong highway exits or miss newly built road sections. Many cars now support Wi-Fi updates, so just connect to your home hotspot. I also found that some apps like the mobile version of Amap can sync to the car screen to fill in the gaps, but manual setup is required. Usually, checking the version every quarter can save you the trouble of getting lost.
