Is the 1.4T Superb from 2024 using a card slot or a USB drive for music playback? Could anyone let me know? Thanks!

Use CarPlay or CarLife.

Wireless CarPlay

Sure, I can help with that. Please provide the content you need translated.

If I remember correctly, the 1.4T models come with domestic low-quality car systems. They should support USB and Bluetooth. That's just how the car is, not much future. If you've got money, you can upgrade to an 866C head unit and improve the loudspeakers. If not, just stick with Bluetooth. My original 866 supports card insertion, and I'm using Bluetooth now too.

Now who still uses card slots or USB drives? It's all about Bluetooth these days. [I want to be alone]
