Where is the AUX interface in Lexus UX?

The AUX interface in Lexus UX is located under the center armrest. Open the armrest to see it. The AUX is an audio input interface. Its basic working principle is that after connecting to the AUX interface, the audio from electronic devices can be transmitted to the car audio system via the headphone jack and AUX interface, allowing playback through the car audio broadcasting facilities. The USB interface can be used to insert a USB drive for audio playback. To use it, connect one end to the AUX interface and the other end to devices like smartphones, 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 3.5mm standard headphone jack). Aux, short for Auxiliary, 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 and CONSOLE port are usually placed together 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 impossible in user mode, such as initialization, restoring default settings, 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. Using the AUX interface, remote configuration and line backup functions for hardware products can be achieved. Note: When using the AUX interface, ensure you purchase the correct connecting cable and avoid inserting the audio cable into the wrong port. It's best to follow the steps outlined in the product's user manual. If unsure, consult the product's official website or customer service hotline.
I've been driving the Lexus UX for over two years now, and every time I listen to music, I use the AUX interface to connect my phone for playback. It's located on the right panel of the center armrest, a standard 3.5mm jack. At first, I also spent quite some time looking for it. My suggestion is to look down at the area between the front seats and gently push open the small cover. Besides this, the UX also supports Bluetooth connection, which offers clearer sound quality and more convenient wireless operation. Regularly clean the interface to avoid dust buildup and poor contact, otherwise, the sound may fluctuate in volume. I've noticed that as the car ages, the wiring tends to deteriorate, so it's important to check the connection stability during each maintenance session. This way, the music won't be interrupted while driving, making the journey much more enjoyable.
As someone who frequently modifies cars, I've noticed that the Lexus UX's AUX interface is typically located either on the inner side of the glove compartment or in a corner beneath the center console, with the exact position depending on the model year. For example, my colleague's 2019 UX model has it hidden inside a small compartment within the glove box—plugging in headphones directly delivers high-fidelity sound. It's advisable to check if the connector is oxidized or has dust buildup, as this can affect audio transmission stability. If the interface feels loose, it might be a wiring contact issue requiring professional equipment to test circuit voltage. Minimizing frequent plugging and unplugging can extend the interface's lifespan, and optimizing settings with the car audio system enhances performance.
