Open the software luchang _diy, connect the SD card to the computer, open Navione and NaviResFile in turn, find the NaviConfig.dll file, and drag it to luchang _diy.

Luchang _diy will display the original navigation information and record the data of HD port on a piece of paper for future use.

Back up the data in the SD card in case the upgrade fails. After backup, format the SD card with FAT32.

Open the downloaded main program of Kay LiDE car navigation. As above, open Navione→NaviResFile in turn, find the NaviConfig.dll file, drag it into Luchang _diy, and modify the data in HD mouth to the data you just wrote on the paper.

Finally, copy the modified HD port and the main program with the map package directly to the SD card. Ok, after the navigation upgrade, plug the SD card back into the car navigation, turn on the navigation, and the familiar picture will appear in front of you.
