the USB interface and AUX interface of Audi music plug-in equipment are located in the storage compartment under the middle armrest and in the front center console. General cars have on-board CD or USB slots. At this point, you can get power from the USB port. Generally, the USB interface has 5V output, but the current is not large enough, so it is used for emergency (about 5MA).

Audi A3 can't play music directly through USB. Because Audi a3 can only use external audio, that is, the connector for inserting headphones. If you want to play songs with usb on Audi A3, it is easier to directly connect the 3.5mm dual-connector audio cable, and then press the cd key on your head to switch. In addition, the speaker grille on the door is made of platinum and aluminum. Through anodizing technology and streamlined appearance, laser technology also engraves BangOlufsen logo on it. In addition, the soft light emitted by the embedded LED lighting system not only visually separates the platinum-aluminum veneer from the dark grille, but also adds a unique white strip to the BO sound system.
