GS4 navigation system upgrade method is as follows: 1. First, download the navigation data file from the official website; 2. Prepare a blank USB flash drive and extract the file to the root directory of the USB drive. After extraction, there will be three files in the root directory; 3. Insert the USB drive into the car's USB port and start the navigation host. Simultaneously press AM/FM and SET, wait for 10 seconds to enter the engineering mode; 4. Click on version information, then click confirm. After the upgrade is completed, click OK, and the host will restart again. The car navigation system has GPS global satellite positioning system function, allowing you to know your exact location while driving. The car navigation system also features automatic voice navigation, optimal path search, and other functions.
I just upgraded the navigation system for my Trumpchi GS4 a few days ago. It was quite simple but required attention to some details. There are mainly two methods: one is manual upgrade using a USB drive. First, go to the download center on the Trumpchi official website, find the map update package for the corresponding model, download it to your computer, unzip it, and copy it to an empty USB drive formatted as FAT32. Then, insert the USB drive into the USB port on the car's central console, open the car door but do not start the engine, turn on the power to put the vehicle into standby mode, select the map upgrade option in the settings menu, and the system will automatically recognize and install the update. The whole process takes about half an hour, and once completed, the new map will be loaded. The second method is to use the new OTA upgrade feature if available. You can connect to a stable Wi-Fi network in the car, check for online update options in the system settings, and simply click confirm to automatically download and install the update, which is more convenient. After the upgrade, the map data feels more comprehensive, reducing the risk of getting lost. Regular updates can make the navigation more accurate and driving more reassuring.
I think the key to upgrading the GS4 navigation system lies in distinguishing the model year, as the methods may differ between older and newer models. Older vehicles mostly require manual USB updates, while newer ones may support OTA online updates. First, prepare a USB drive with at least 16GB of storage and download the latest official map package on your computer—avoid using pirated files to prevent system errors. Next, turn off the car engine but keep the power on, enter the settings, select "System Tools," and click "Map Update." Once the process starts, avoid touching any in-car devices and wait for the system to reboot automatically. After the upgrade is complete, test the navigation route for accuracy to ensure safe driving. If you encounter issues, remember to check the USB drive format or refer to the user manual. During the upgrade, never turn off the engine or cut power to prevent damage to the infotainment system. Regular updates can improve travel efficiency, especially for long-distance trips, as updated road names are more accurate, helping you avoid wrong turns and wasted time.
