Ensure you have your vehicle's model and the current software version (9.1.3) ready to input when checking for updates.
Version 9.1.3 is quite old (released around 2017/2018). If your car has a newer version installed (e.g., 10.x or 11.x), you cannot downgrade to 9.1.3. Attempting to do so can cause the system to malfunction. media nav evolution 9.1.3 aktualizacja
