Solution

1. Preparation

Ensure the vehicle is parked in a safe location and the ignition is turned off.
Gather necessary tools, including a clean microfiber cloth and a soft brush for cleaning.

Use a microfiber cloth to gently clean the screen, removing any smudges or dirt that may affect touch sensitivity.
For stubborn spots, lightly dampen the cloth with water or a screen-safe cleaner.

3. Update Infotainment Software

Navigate to the 'Software' settings on the infotainment screen.
If an update is available, follow the prompts to download and install it, ensuring the vehicle is connected to Wi-Fi.
Allow the system to reboot after the update process is complete.

4. Check Hardware Connections

Open the center console and inspect USB connections for any damage or loose connections.
If necessary, reseat or replace USB cables that are not functioning properly.

If problems persist, consider performing a factory reset. Go to 'Settings', select 'Reset', and then choose 'Factory Reset'.
Note that this will erase all personal data and settings, so ensure a backup is made if possible.
