If you use the original navigation of Volkswagen LaVida, that is, the navigation of Desai Siwei, enter Desai Siwei official website on the Internet, and enter official website to download the map, with instructions on related operations. If the navigation is an SD card, you can take out the SD card and connect it to the computer through a card reader.

And copy the previously downloaded navigation map file to SD card, overwriting the original map file. Modify the port and baud rate. You can use it. Before copying the new map file, please pay attention to backup all files of the original SD card.

Generally, there are two types of navigation equipment upgrades.

One is the car machine products produced by the original factory, which must be upgraded in the original 4S shop to avoid the warranty being damaged when the original product upgrades the navigator by itself. The other is the rear loader product purchased by users themselves, which is relatively simple to upgrade and can be downloaded and installed directly in official website.

Because there is no interface for easy upgrade in the old lathe products, such as SD card, when upgrading, the products need to be connected with specific USB or other devices to write new data into the products; Modern new car products can be upgraded through SD card, and the corresponding upgrade card can be purchased in 4S shop.
