1. First, take your navigation card out of the car, delete all the old navigation files in the navigation card, and remember the folder name of the navigation card root directory before deleting it;
2. Then find the latest version of Kay LiDE navigation at night. At present, the latest version is version 5.0 of C car, and the drawing is C 25 15-c7k 03-3225 JK. The downloaded file is NaviOne. First, change it to the name of the original root folder corresponding to your navigator. Mine is MobileNavigator, just modify the file name here.
3. Then open the folder and replace NAVIONE in three files in NaviOne.dllNaviOne.exeNaviOneSCH.dll with the folder name of the navigation root directory.
4. The last step is to open the Khalid navigation port modifier, modify the Naviconfig.dll file in the NaviResFile folder, and change the navigation port and baud rate to those corresponding to your navigation.
The above is for reference only, I hope I can help you.
