Bluetooth FM Transmitter MP3 Player

This universal car audio adapter measures approximately 1.3 inches (diagonal) for the dot matrix LCD screen and is constructed from durable plastic. It operates within a wide voltage range of 8–27 V DC (rated 12–24 V), making it compatible with most cars, vans, and commercial vehicles across the UK and EU. The device supports dual USB output delivering a combined 5 V / 3.1 A — sufficient to charge smartphones and other USB-powered devices while in use. Audio performance includes a frequency response of 20 Hz–15 kHz, signal-to-noise ratio of 60 dB, channel separation of 60 dB, and total harmonic distortion under 0.1%. Bluetooth 4.0+ enables stereo music streaming via A2DP and hands-free calling with echo cancellation and noise suppression; microphone pickup is effective at 0.5–2 metres. FM transmission covers the full UK/EU broadcast band (87.5–108.0 MHz) using stereo digital PLL frequency lock. It plays MP3/WMA files from USB flash drives or microSD (TF) cards, supports multi-language UI, adjustable display contrast, real-time voltage detection (±1 V accuracy), and auto power-off memory retention. Ideal for drivers seeking a reliable, all-in-one audio upgrade for older cars without AUX/Bluetooth — especially those who frequently switch between music playback, hands-free calls, and FM radio transmission. Works seamlessly with UK-spec vehicles and meets standard automotive electrical tolerances.
