Where is the AUX interface located in the Audi A6L?

The AUX interface of the Audi A6L is located in the center armrest box. The AUX is an audio input interface. The basic working principle of the AUX interface is that after connecting to it, the audio from electronic devices can be transmitted through the headphone jack and the AUX interface to the car audio system, allowing the audio to be played through the car's audio broadcasting facilities. The USB interface can be used to insert a USB flash drive for audio playback. When using it, connect one end to the AUX interface and the other end to devices such as mobile phones, MP3 players, or MP4 players. This allows you to listen to songs or niche music anytime, anywhere, without being limited to car music CDs. However, if the playback device runs out of power, the music will stop (the interface is typically a standard 3.5mm headphone jack). Aux is short for Auxiliary, which refers to an additional signal line design. In general audio equipment, besides the standard output and input terminals, there are often several terminals labeled Aux, serving as backup connection points. These can be used for special applications, such as additional audio output or input. Such backup terminals or lines, whether for input or output, are collectively referred to as Aux. Function: The AUX port is an asynchronous port, mainly used for remote configuration, dial-up connections, or connecting to a MODEM via a transceiver. It supports hardware flow control. The AUX port is usually placed together with the CONSOLE port because they are used in different configuration environments. The AUX interface establishes a command-line connection between the user and the device, enabling operations that are typically not possible in user mode, such as initialization, restoring default configurations, or correcting abnormal user modes. It provides a fixed port for the device, which can be used as a standard asynchronous serial port with a maximum speed of 115200bit/s. With the AUX interface, remote configuration of hardware products, line backup, and other functions can be achieved. Note: When using the AUX interface, make sure to purchase the correct connecting cable and avoid plugging the audio cable into the wrong port. It is best to follow the steps outlined in the product's user manual. If you are still unsure, you can consult the product's official website or call customer service for assistance.
I've been driving an Audi A6L for five years, and locating the AUX port does vary by model year. For older C6 models like those around 2008, the port is usually on the inner wall of the glove compartment on the passenger side or near the ashtray at the bottom of the center console, resembling a headphone jack. For the C7 models from 2012 to 2018, most have it tucked deep inside the center armrest—just pull it open to spot the silver circular port. The latest C8 model is trickier; it might be hidden in a compartment layer within the armrest, requiring removal of the storage tray to reveal a small black port. A quick tip: check the 'Media Source' option on the center console screen—if AUX appears as an option, the port definitely exists. If you still can't find it, snap a photo of the armrest interior, and I can help identify it—some aftermarket installations may relocate the port.
