Open the resource link, download the file, and copy the downloaded file to the root directory of the USB drive. Before copying, ensure the USB drive is emptied and formatted. Press and hold both the MENU and NAV buttons simultaneously for 5 seconds. The central control system will then display the system upgrade interface. Proceed by selecting 'Software Upgrade', followed by 'Master Control Upgrade'.
I love tinkering with car electronics, and upgrading the large-screen navigation system is actually not difficult. Most car models have an update package download page on their official website. You just need to enter the model and year, then download the software to your computer. Prepare a blank USB drive, format it, and drag the files into it, making sure the format is FAT32. Then plug it into the car's USB port, start the engine to keep it running, enter the settings menu to find the system update option, and click it to start the upgrade. During the upgrade process, avoid pressing any buttons or turning off the car to prevent failure. After completion, the system will restart, and you should test whether the navigation function works properly. Usually, updating once every one or two years ensures the map data is up-to-date and helps avoid detours. Some high-end models even support wireless OTA updates—just connect to the internet, but make sure the signal is strong for convenience.
