QC3.0 Bluetooth FM Transmitter with Dual USB Charging and TF Card Support

This QC3.0 Bluetooth hands-free car MP3 FM transmitter lets you use your phone safely while driving by streaming calls and music through your existing car radio. It plugs into the cigarette lighter socket and starts up automatically, with the LCD showing the car battery voltage. Pairing is straightforward: the transmitter appears as "T43" on your phone, and a voice prompt confirms a successful connection. Once paired, you can answer, hang up, reject, and redial calls, listen to Bluetooth stereo music, and see caller ID on the display. The dual USB ports provide 5V/1A and 5V/2.4A charging recognition, and the TF card slot supports cards from 1 GB to 32 GB. The FM transmitter covers 87.5 to 108.0 MHz, so you can find a clear frequency on your car radio. Additional features include voice prompts for mobile navigation, voice assistant activation, aux in/out, dot matrix display, and an auto power-off memory function. This unit is suited to drivers who want hands-free calling and music playback without replacing their car stereo.
