The AUX interface of Tiguan is located on the inner wall of the center console armrest box. The AUX interface (Auxiliary) refers to an audio input interface that can connect to electronic audio devices including MP3 players, allowing the car's sound system to output music from these devices. In some models, the AUX interface can both input and output audio, while in others, it can only input audio. How to use the AUX interface: First, prepare a playback device (such as a computer, phone, or MP3 player) and a single-to-single 3.5MM audio cable. Then, connect one end of the 3.5MM dual-head cable to the headphone jack of the phone or MP3 player, and the other end to the car's AUX port. After connection, turn on the car's media player and switch to AUX mode, then play directly. It should be noted that the AUX interface is different from the USB interface. The AUX interface can only connect to external audio devices for audio playback, with the power amplifier handled by the car's audio system. The USB interface has more functions than the AUX interface, as it can connect to more external devices for data transfer, file copying, etc. However, in terms of audio playback alone, the sound quality through the AUX interface is better than through USB. The sound quality of AUX is similar to that of a CD.

There's a clever little spot hidden in the armrest of my 2018 Tiguan! When you lift the lid, you'll spot this small circular AUX port with a reminder label right beside it. The location actually varies by model year - my friend's older version has it in the storage tray beneath the center console. Pro tip: before frantically searching, adjust your seat backward to give yourself better visibility when bending down. If you still can't locate it, I recommend using your phone's flashlight (with engine off) to check side seams of the glove compartment or hidden slots near the cigarette lighter. One important note - this port collects dust easily. Clean it occasionally with cotton swabs to maintain clear audio quality. I learned this the hard way when poor contact ruined my listening experience last time.

Based on my experience with four or five Tiguan models, the AUX ports are mostly located in two positions: 80% of the models have it at the bottom inside the center armrest compartment—just lift the anti-slip mat to find it. The remaining 20% place it in the open storage tray below the air conditioning panel. Recently, while helping my neighbor check his 2020 model, I discovered the port was hidden in a left-side compartment of the glove box. I recommend starting your search from the armrest, paying special attention to the rear wall near the air vents. If you're traveling with kids, this port is perfect for connecting a tablet to play cartoons—far more convenient than using the car's .

I'm familiar with locating the AUX port! Just recently helped a colleague with this. Touguan owners, pay attention to three things: First, check the inner wall of the center console for a silver circle; second, inspect the small compartment in front of the gearshift; finally, don't miss the recessed area on the right side of the glove box. Newer models might use a Type-C port instead of the old round one. If there's no sound when connected, try turning your volume to maximum before adjusting the car audio system volume. For cables, I recommend using ones with ferrite cores – I've compared them with generic cables and the current noise is noticeably worse with cheap ones.

Last time at the 4S shop workshop, I saw a Tiguan getting a dash installed and casually asked the mechanic about the AUX port location pattern. He said for models from the past five years, it's basically inside the center armrest box, but comes in three variations: a slot at the box bottom, a recess on the left inner wall, or the top area when the lid is flipped open. When searching, feeling around the box walls is more effective than looking – many owners mistake small protrusions for screw holes. Bonus tip: If the cable's too long, use Velcro to tie it to the pull ring inside the box to prevent tangles.

The AUX design of the Tiguan is quite user-friendly. Mine is hidden on the vertical surface at the front of the armrest box. However, when helping car club members with repairs, I found that pre-2015 models often have it in a horizontal row position on the upper edge of the glove box. Reminder for connection: 1. Confirm the car stereo is switched to AUX mode (select EXT as the media source). 2. Apple phones need to have the playback app enabled. 3. Android users should remember to turn off USB debugging mode. If there's poor cable contact, try twisting the plug a few times—it's more effective than reinserting it.
