The -up command is: "Hello BMW". The voice system generally enables the following functions: Navigation Search: Set destinations, route preferences, etc., via voice commands to configure navigation. It is recommended to use this feature when the vehicle is parked. Music Playback: The onboard computer automatically searches for and plays relevant music based on voice commands. It is advisable to maintain a moderate volume while driving to prevent the audio from overpowering external environmental sounds and avoid potential hazards. Phone Calls: After connecting your phone to the car, you can directly make calls via the onboard computer. It is recommended to minimize voice calls while driving to maintain focus and ensure driving safety.

When I first got my 3 Series, I learned to use the voice function. The wake-up command is 'Hey BMW', and it activates iDrive as soon as I say it. The first time I tried it in the garage, it responded immediately, allowing me to ask for directions or adjust the temperature. New user settings can be quickly completed in the screen menu, and it also supports Chinese commands like 'Start Assistant', but I find English more accurate. The system is easy to use, with strong voice recognition, even with a slight accent. BMW designed this little command thoughtfully, keeping the focus on driving without adding hassle.

Comparing voice systems across different car brands, BMW's -up command 'Hey BMW' stands out. It activates more easily than Audi's 'Hey Audi' or Mercedes' 'Hey Mercedes', with faster recognition and better performance in noisy environments. BMW offers the flexibility to customize the wake-up command in iDrive settings, while most other brands have fixed phrases. In my experience, the audio optimization is well-executed, enhancing driving comfort. BMW is also upgrading its AI, suggesting future commands may become more intelligent.
