Audi A6 front row USB port is installed inside the glovebox CD case cover on the right side of the dashboard, while the rear USB interface is hidden in a box beneath the rear seat air conditioning. Below are precautions for using USB ports: 1. Avoid hot plugging: Hot plugging ≠ random plugging/unplugging. Do not remove the USB drive during data reading/writing to prevent damage to both the drive and port. 2. During usage: USB drives require driver loading during operation. If occasional recognition failures occur with drives or phones, try reconnecting. Remove unused USB drives promptly to prevent accelerated aging, as the host system frequently accesses them, affecting operational speed. 3. On bumpy roads: Vehicle vibrations may cause unstable USB connections leading to disconnections. Wait patiently for system reconnection or replug the USB drive/phone.

When I usually drive this car, I often use a USB flash drive to listen to music, and the location is very easy to find. It's in the small storage compartment in front of the front center console. Open the cover, and you can see two ports: one is the traditional rectangular USB-A port, and the other is the oval-shaped Type-C port. The USB-A port is the most commonly used; you can directly plug in a regular USB flash drive. After plugging it in, tap the media source icon in the upper left corner of the infotainment screen and select the USB device to play songs. There's actually another Type-C port inside the armrest compartment, but that one is for charging only and cannot transfer data. It's recommended to format the USB flash drive to FAT32 for the best compatibility. Also, be careful not to plug or unplug the drive while driving; it's safer to do so when parked.

My 2021 A6L has been in use for almost two years, and I mainly use the USB port located in the area below the center console. Specifically, it's inside the hidden panel in front of the gear shift lever—just press lightly and the cover will pop open. There are two ports side by side; the one on the left with a small triangle symbol is the data port, which can directly read a USB drive when connected. If it fails to recognize the USB drive, I recommend checking the drive's format—FAT32 is preferred over NTFS. The port inside the armrest is only for charging and won't respond to a USB drive. By the way, it's advisable to turn off your phone's Bluetooth when using the USB drive to avoid system errors that might switch the audio source and disrupt playback.

Using a USB drive with this car is incredibly simple. Just locate the storage compartment in front of the gear lever. Lift the cover to reveal two ports - insert your regular USB drive into the rectangular USB port. After insertion, tap the Media button on the main screen and select USB under External Devices. Note: Avoid storing music files in too many nested folders as this may slow down the infotainment system's recognition. The port with a lightning symbol inside the armrest is exclusively for fast charging and won't recognize USB drives. For optimal performance with permanently connected USB drives, periodically format them to clear fragmentation and prevent lag.
