🔍 How to check your firmware version?

Before purchasing, please verify that your Audi A1 is equipped with the MMI 3G Plus (Hard Drive-based) system:

1. Press the MENU (or SETUP) button.
2. Navigate to Settings -> Version Information.
3. How to verify? Your current version must start with HN_EU_AU210_. If your version is lower (e.g., K0767, K0800), this K0900 update is the official and final path for your vehicle.

Note: This update is specifically for the AU210 line (Audi A1). Do not attempt to use this on other Audi models even if they have MMI 3G Plus.
