does not support wireless CarPlay, but it does support wired CarPlay systems. CarPlay is an in-car system released by Apple Inc., which seamlessly integrates users' iOS devices and iOS experience with the dashboard system. Mercedes-Benz is a German automobile manufacturer with a wide range of sedans and SUVs, many of which have been locally produced in China. The locally produced models of Mercedes-Benz include the A-Class, C-Class, E-Class, GLA, GLB, GLC, and GLK. Taking the Mercedes-Benz A-Class as an example, it is equipped with three engines: a low-power 1.3-liter turbocharged engine, a high-power 1.3-liter turbocharged engine, and a 2.0-liter turbocharged engine. The A-Class retains its original design style, with a rising waistline, enlarged window area, prominent and smooth side lines, flared wheel arches, and a series of emphasized horizontal lines, making the new A-Class more eye-catching on the road.

As an owner of the 2021 C-Class, I find wireless CarPlay really convenient—it automatically connects for navigation and music playback without needing to plug in a cable. However, I’d like to remind you of three things: First, check if your car’s infotainment system supports wireless functionality, as pre-2020 models usually require a wired connection. Second, you must use an iPhone with the latest iOS version to avoid frequent disconnections. Third, remember to pair Bluetooth via the 'Smartphone' settings on the central display. Last week during a long drive, I noticed occasional wireless lag, but restarting the infotainment system after parking fixed it. New owners should confirm details with their dealership salesperson, as configurations vary significantly across model years.

A technician with 10 years of repair experience reminds: Wireless CarPlay compatibility depends on specific configurations. Newer models with MBUX systems like GLC/E-Class usually have it as standard, but most COMAND systems before 2020 don't support it. If you encounter connection issues, don't panic—first ensure your phone's Bluetooth and WiFi are both turned on, as wireless CarPlay actually transmits data via WiFi. If the CarPlay icon appears grayed out on the screen, it's likely the car's network isn't activated; simply reset the network module in the settings to fix it. A common mistake regular customers make is forgetting to turn off their phone's hotspot, which can also interfere with the connection.

When conducting in-car system testing for before, we found that the stability of wireless CarPlay varies significantly across different models. High-end models like the GLE rarely experience dropouts when using the 5GHz frequency band, while entry-level A-Class models occasionally suffer from interference. Here's a little-known tip: Simultaneously using in-car wireless charging can affect transmission speeds, so it's better to choose one or the other. Our tests show that iPhone 12 and later models have better compatibility, while older phones may benefit from a CarPlay adapter. Currently, authorized dealers offer paid module installations for around 3,000 RMB.

When researching car cabins, I noticed Mercedes' CarPlay strategy: vehicles supporting wireless connectivity after 2018 come with a WiFi antenna on the left side of the steering wheel, offering 30% faster transmission than BMW. However, there are two pitfalls to avoid: first, setting the system language to anything other than Simplified Chinese may cause it to malfunction; second, the vehicle's software must be updated to the latest version, especially the 2022 update which resolved music stuttering issues. Some customers reported delays in the reversing camera when connecting to CarPlay, which is actually caused by insufficient memory in the car's system—simply clearing background applications can fix this.

Comparing the CarPlay experience among the German Big Three, Mercedes' wireless functionality is truly impressive in the new models. Like during last week's test drive of the new C-Class, the automatically projected the screen as soon as I sat in the driver's seat. However, three points require special attention: 1. Base models may lack the antenna module; 2. For used cars, check the original factory configuration sheet to confirm; 3. Installing aftermarket modules will void the warranty. A friend bought an 'original module' on Xianyu but ended up blowing a fuse. For safety, it's recommended to use Mercedes' official VIN code query system for verification, or directly call the 400 customer service hotline to verify with the chassis number.
