Vehicle Integration: Perfect for cars with a 3.5mm Aux input but no Bluetooth. The spring cable design keeps the dashboard clutter-free.

Physical Installation:
Power Connection: Insert the USB-A connector into a car charger or USB power source. The device powers on with the ignition.
Audio Connection: Plug the 3.5mm jack into the “AUX-IN” port of your stereo system.

The UGREEN 70603 features intelligent logic for seamless user interaction without complex setup:
Dual Mode Logic: Automatically switches to TF Mode when a card is inserted. Without a card, the device defaults to Bluetooth Mode.
