Bluetooth 5.4 FM Car Transmitter — 38W PD & QC3.0 Dual USB Charger, Microphone, Bass Boost, MP3 Player & Hands-Free Calling

Compact FM transmitter from Synwire that turns your vehicle stereo into a Bluetooth hands-free and music streaming hub. It uses Bluetooth 5.4 for quicker pairing and a more stable wireless link, letting you stream navigation voice prompts (navigation app / Siri / Google Assistant) and phone audio to your car speakers over FM. Charging and power: Supports PD 3.0 & QC 3.0 fast charging with two simultaneous outputs — a Quick Charge 3.0 USB port and a Type-C PD 20W port. The maximum total power can reach 38W, so the charger efficiency is 80% more than normal charger. Synwire provides a high-speed, convenient charging experience for two devices at once. Audio features: Hi‑Fi playback with a dedicated bass‑boost key enhances low-end response, and ambient blue LED backlighting pulses to the beat of your music. Built-in MP3 playback and an integrated microphone enable hands-free use while maintaining better call clarity. Calls and controls: Noise Suppression (CVC) reduces background noise for clearer hands-free calls. A single multi-function button handles answer/reject/end/recall operations so you can switch between calls and music without hassle. Compatibility and fit: Works with any Bluetooth-capable device including iPad, iPhone, iPod, HTC, Galaxy, Sony, MP3 players, tablets and Android smartphones. Fits 12V-24V cars and trucks. Notes and quick tips: If you hear static interference, try a different FM frequency and repeat the setup steps. To adjust volume via the transmitter: 1) Double-click the multi-function (calling) button — the channel display will flash. 2) Rotate the knob left or right to lower or raise the volume.
