How do I set up the Nulaxy Bluetooth FM transmitter in my car?

Plug the Nulaxy KM18 into your car's 12V or 24V cigarette lighter socket. Tune your car radio to an unused FM frequency. Then, pair your smartphone via Bluetooth to 'KM18' or insert a TF card. The device will automatically detect your car's voltage and display information on its LCD screen.

Will this Nulaxy FM transmitter work with my Indian car and phone?

Yes, this Nulaxy transmitter is designed for universal compatibility. It uses the standard 87.5-108 MHz FM band used in India and connects to any Bluetooth-enabled smartphone or device. It fits standard 12V-24V car sockets common in Indian vehicles, ensuring broad usability.

Can I play music from both my phone and a USB drive?

The Nulaxy KM18 supports multiple playback modes. You can stream music wirelessly via Bluetooth 5.0 from your smartphone or tablet, or play MP3 files directly from a TF (microSD) card inserted into the dedicated slot. It also features an Aux input for wired connections.

How clear are the hands-free calls with this device?

The Nulaxy KM18 features a built-in microphone with noise-cancellation technology. This helps to reduce background road noise, ensuring your voice is clear to the person on the other end during hands-free calls. A single button allows you to answer, reject, or redial calls.
