Scosche KM18 Bluetooth 5.0 FM Transmitter

The Scosche KM18 is a Bluetooth 5.0 FM transmitter designed for drivers who want wireless audio streaming and hands-free calls in vehicles without built-in Bluetooth. It connects to the car stereo via an FM frequency or the included 3.5mm AUX cable. The 1.44 inch LCD display shows caller ID, FM channel, music info and car battery voltage. It supports TF card playback and fits 12V-24V vehicles.

1.44 Inch LCD Display and Noise Cancellation

The 1.44 inch LCD display provides clear visibility of phone calls, FM channels, music data and vehicle battery voltage without distracting the driver. Built-in noise cancellation technology reduces road noise for clearer hands-free conversations. Bluetooth 5.0 offers a stable, fast connection with fewer dropouts. The flexible gooseneck allows adjustable positioning for optimal viewing and microphone pickup. Music streams via Bluetooth, TF card or AUX input.

Simple 12V Installation and Common Issues

Plug the transmitter into the 12V-24V power outlet, tune the car radio to an unused FM frequency and match the device to the same channel. Pair a phone via Bluetooth 5.0 or insert a TF card for instant playback. The single multifunction button handles call answer, reject, hang-up and redial. Common issues include FM static in dense signal areas, which the AUX cable bypasses, and occasional pairing delays if the manual steps are skipped.

Questions about this item

Will the 1.44 inch LCD display need replacement after extended use?

The display is a fixed part of the unit and is covered by the one year parts warranty; no user serviceable replacement is designed for the screen.

What limits continuous hands-free call quality on long drives?

The built-in microphone and noise cancellation system set the practical limit; performance depends on cabin noise and phone signal strength.

How much heat does the transmitter generate when running all day?

The device draws power from the 12V-24V socket for Bluetooth 5.0 operation and the LCD backlight; it runs warm but stays within normal operating temperature.
