Format the USB drive to FAT32 and copy the software update files onto it.
Insert the USB drive into the vehicle's USB port.
Turn on the ignition and access the settings menu on the infotainment system.
Follow on-screen instructions to perform the software update.

4. Soft Reset of Infotainment System

Turn the vehicle ignition to the "On" position without starting the engine.
Press and hold the “Power” button on the infotainment system for approximately 10 seconds until the system restarts.
Wait for the system to fully reboot and check if the navigation system starts functioning.

5. Check GPS Signal

Ensure that the GPS antenna is properly connected and not obstructed.
Drive the vehicle to an open area away from tall buildings or trees, and wait a few minutes for the system to acquire a signal.
Check if the navigation screen starts displaying the correct location.
