Does anyone know how to download the upgrade assistant for travelers? I need it urgently ... thanks.

1. Run the LXZAssistant.exe file directly on the computer after decompression.

2. Change the download location of the file set in the path on the computer.

3. Select the brand and model of the machine in the product settings. Click Upgrade Online.

4. Select the content to be updated in the upgrade content check box, and then click Update to start downloading. If the program can be used normally, please only select the map to be updated, and don't choose anything else. Other contents have not been updated for the time being. If the download speed is not displayed for a long time, please change a download mode in the download mode and try downloading again.

5. After the map download 100% is successful, you will be prompted to insert the SD card or connect the machine, and follow the prompts. The assistant software will be automatically decompressed and replaced in the memory card to complete the update.
