It is intended for systems using a 3.5 mm auxiliary audio connection rather than replacing the radio itself. The adapter lets a compatible Bluetooth-enabled mobile device send music to the connected sound system.\u003c\/p\u003e\u003cp\u003eThis adapter is a practical option for listeners who have an older head unit without built-in Bluetooth. It supports Bluetooth 4.0 music streaming and uses the A2DP audio profile for wireless playback. Music selection and volume adjustment are handled from the paired mobile device.\u003c\/p\u003e\u003cp\u003eThe AT-SN4BT is designed for a clean installation with the receiver concealed behind a dash, panel, or other protected location. Its compact, hidden-install approach can help retain the factory appearance of a vehicle or vessel. The product is described as waterproof and suitable for marine applications, although no IP rating is published.\u003c\/p\u003e\u003cp\u003eFor day-to-day convenience, the adapter supports automatic switching and reconnection to the last paired device. It can connect with multiple Bluetooth devices, but only one device can stream audio at a time. If the active device remains disconnected for more than one minute, the adapter enters pairing mode.\u003c\/p\u003e\u003cp\u003eThe AT-SN4BT fits into a system through USB power and a 3.5 mm audio connection to the radio or sound system. It also provides an automatic 12-volt remote-output function while Bluetooth is active and music is playing. This makes it useful in installations where a connected accessory needs a low-current remote turn-on signal.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth 4.0 Streaming:\u003c\/strong\u003e Adds wireless music playback from compatible mobile devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA2DP Audio Profile:\u003c\/strong\u003e Supports Bluetooth stereo audio transmission for music listening.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.5 mm Audio Connection:\u003c\/strong\u003e Integrates with compatible car and boat radios.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB Power Connection:\u003c\/strong\u003e Powers the adapter through a USB connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Reconnection:\u003c\/strong\u003e Remembers and reconnects to the last paired device.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12V Remote Output:\u003c\/strong\u003e Provides a low-current remote signal during active playback.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe AT-SN4BT is a compact receiver intended for concealed installation, helping keep the cabin or helm area free of visible cables and added controls.
