Here is an introduction to the software and functions of MOS: 1. Voice Control: The SAIC MOS 3.1 infotainment system is equipped with a new voice assistant. In addition to activating the voice assistant via the steering wheel, it can also be activated using a wake-up phrase, with quick response times. The default wake-up phrase is "Hello Volkswagen." 2. Navigation: The new navigation system is powered by AutoNavi (Gaode) Maps, offering the same user experience as the AutoNavi app on mobile phones. It supports features such as real-time traffic updates, alternative route suggestions for congestion, and avoiding restricted zones. Navigation information can also be projected onto the full LCD instrument cluster for full-screen display or shown in a split-screen format on the virtual instrument panel. There are ample display positions for the driver to observe navigation, making this design feature highly user-friendly.

The screen in my Passat displays the MOS system, which is actually SAIC Volkswagen's intelligent vehicle infotainment system. It integrates functions like entertainment, navigation, and vehicle settings all into one large screen. For example, the voice control is quite convenient—just say 'Navigate to Hongqiao Airport' and it automatically plans the route. After last week's OTA update, it even added the Huawei AppGallery download feature, allowing direct installation and use of apps like Himalaya and NetEase Cloud Music. This system is far more advanced than the old car radios in previous models.

SAIC MOS stands for 'Magic Oil Space.' Sounds magical, right? Actually, it's their intelligent connectivity system. Like in my Lamando L, I noticed right after picking up the car that this system controls the entire central display, connecting to both CarPlay and Huawei HiCar. After the recent system update, it even supports gesture control—just wave your hand in front of the screen to switch songs. However, the voice assistant initially struggled with dialect recognition, but it improved a lot after a system upgrade.

I've studied SAIC Volkswagen's MOS system, which is essentially an in-vehicle terminal. It consists of three core modules: MOS 3.0 handles intelligent interaction, MOS 4.0 manages cloud connectivity, and MOS for Mobile enables smartphone integration. In practical use, the air conditioning temperature adjustment is most convenient - just say 'lower the temperature'. The system proactively provides road speed limit alerts while driving, demonstrating excellent safety features.

In our car enthusiasts' group, we discuss this MOS system every day. New car users report that it allows customization of the dashboard layout. For example, projecting navigation maps onto the screen in front of the driver's seat. Actual tests show a speech recognition rate of around 85%, with quick responses to commands like 'turn on seat heating.' Recently, a hidden feature was discovered: holding down the steering wheel voice button for ten seconds can reset the voice system. Many friends chose the new Passat model specifically for this intelligent system.

The MOS system has evolved through three stages. The early version only had basic functionality, but now it has been upgraded to version 4.0. The key improvement is the integration of smart home control, allowing you to turn on the air conditioner while driving home. Once, I tried using voice commands to order coffee, and the system automatically navigated to the nearest Starbucks. Although occasional lag may occur, the overall smoothness is much better than that of Japanese cars in the same price range.
