The Yesido YAU40 is the perfect bridge between your smartphone and your classic car audio system. Simply plug the USB end into a power source and the 3.5mm jack into your AUX port, and you’re ready to stream Spotify, Apple Music, or Podcasts wirelessly.
Innovative Double-Blind USB Design
Tired of fumbling with USB plugs in the dark? The YAU40 features a Reversible (Double-Blind) USB interface. Unlike standard USB plugs that only go in one way, this innovative design allows you to insert the plug into your car charger or laptop correctly on the first try, every time.
Crystal Clear Hands-Free Communication
Safety meets convenience. The YAU40 isn’t just for music; it features an intelligent noise-reduction microphone. When a call comes in, you can answer it directly through your car’s speakers, ensuring your hands stay on the wheel and your focus stays on the road.
Superior Signal Stability
Equipped with a Bluetooth 5.0 chip, this adapter eliminates the lag and stuttering common in older receivers. Whether you are using an iPhone or Android device, you’ll enjoy a synchronized audio experience perfect for watching videos or gaming during long road trips.
Built to Last
The cable is crafted from high-resilience TPE material. The spring-coiled design is specifically made for vehicle environments, preventing tangles and ensuring the cable doesn’t hang loosely over your gear shifter or console.
