Car FM Transmitter with LCD Display, 15m Range and Hands-Free Calling for Android and iPhone

This compact FM transmitter provides a straightforward way to play music and take calls in older cars without Bluetooth. It connects via the standard 3.5mm headphone jack, making it compatible with virtually any smartphone or MP3 player. The device uses DIGITAL PLL phase-locked loop technology to deliver high-fidelity stereo sound, with a transmission range of up to 15 metres for a strong signal. An LCD screen displays the current frequency, and up to 200 frequencies are available across the full FM band (87.5–108.0 MHz). The transmitter stores the last used frequency, so you do not have to reset it each time you get in the car.

Features and Construction

Built around reliable digital transmission technology, this transmitter is designed for everyday use. Its compact body houses a rechargeable lithium battery and a clear LCD display.

Digital PLL Technology

The DIGITAL PLL phase-locked loop system locks onto the selected frequency precisely, reducing drift and ensuring consistent stereo separation of at least 38dB. Audio input response ranges from 100 to 15000Hz, covering the full range of music and speech.

LCD Display and Frequency Selection

A backlit LCD screen shows the current FM frequency, making it easy to tune manually. You can choose from up to 200 frequencies within the 87.5-108.0 MHz band to find a clear channel free from local radio stations.

Power and Battery

An internal 120 mAh lithium battery powers the device. It is rechargeable via a standard USB lead (not included). The transmitter operates at an output voltage of 5 ± 0.1V and draws a vehicle current of ≤600mA. It works in temperatures from -10°C to +40°C and can be stored between -20°C and +50°C.

Uses and Placement

This transmitter suits anyone who wants to add wireless audio streaming and hands-free calling to a car with only a 3.5mm aux input or no aux jack at all. It is particularly useful for older vehicles or hire cars.

Music Streaming

Plug the transmitter into your phone’s headphone jack, tune it to a free FM frequency, and set your car radio to the same frequency. Music from your phone plays through the car speakers instantly. The 15-metre range means the signal stays strong even if the phone is in a bag or pocket.

Hands-Free Calling

When a call comes in, your phone’s built-in microphone picks up your voice while the caller’s audio comes through the car speakers. This allows safer, hands-free driving. Note that the transmitter itself does not have a microphone, so keep the phone within easy reach.

Benefits and Buying Value

This transmitter offers a simple, cost-effective upgrade for car audio systems that lack Bluetooth or auxiliary inputs. Its user-friendly controls and wide frequency range make it practical for everyday use.

Frequency Memory Function

The power-off memory stores the last used transmission frequency. Every time you start the car, the transmitter automatically returns to that frequency, so you do not have to search for a new channel each journey.

Why Choose This Product

With 200 selectable frequencies, a strong 15-metre transmission range, and support for all 3.5mm-output devices, this transmitter is a versatile choice. The LCD display makes setup straightforward, and the compact size means it does not clutter the dashboard.
