Product Description

Important Notice

If you experience *** Unexpected Disconnection *** for Newest iOS or other OS, please watch the troubleshooting guide on YouTube to fix the issue:


Nulaxy KM20 Bluetooth In-Car FM Transmitter is developed based on KM18, one of the most customers favorable bluetooth car kit. The new KM20 is designed to keep KM18's stability, but with a modern sleek design. It features a big display screen, and it is the first to use cellphone keys to bring a higher level of experience. The KM20 utilizes Bluetooth 3.0 technology, and equips with one USB charge port, one USB flash drive port, FM tuner, Aux in and out.

Smartphones could be connected to KM20 through Bluetooth, and then streamed through car FM system or the Aux port. Smartphones or MP3 players could also be connected to KM20 through Aux-in port of the device, and then steamed to car stereo speaker through FM. It provides multi-solutions for your hands-free driving and in-car stereo streaming.

How to Use:

Plug KM20 into car cigarette lighter, it will turn on automatically. Screen will display the voltage of car battery. To use this device, you will have to either sync it to your car FM radio frequency, or connect it to your car Aux-in port (not allvehicles have Aux-in) using enclosed 3.5mm audio cable. You can hold the phone button for five seconds to sleep or wake up KM20.

Please be Note:

1. You can press and hold the mufti-functional button for 8-10 seconds to switch languages.
2. Find a vacant or non-interfered frequency and sync Nulaxy to that frequency for minimized static noise.
3. To achieve best audio quality, please set the volume on your phone to maximum and then adjust the volume for your car stereo; you are not suggested to adjust volume of your car speaker to maximum (this will bring lot noise).
4. To protect this device, we recommend to remove it from cigar outlet after use, to avoid instant high start voltage damage the device.

Long press the [Mode] button, you can switch three playing modes:

Normal: songs play in the song list order;
Shuffle: songs play in random order;
Repeat 1 Song: current song or selected song play repeatedly.

Note: Normal / Shuffle / Repeat play modes are intended for TF card and USB flash drive play. (songs played through Bluetooth don't support those play modes).

Hands-free phone call is priority over all options. After you pair your phone to KM20, you can short press [Phone] button to answer phone calls; you can long press [Phone] button 3 seconds to reject incoming call; you can short press [Phone] button twice to redial the last phone number.

KM20 supports music play through Bluetooth, TF card or USB flash drive. You can short press the [Mode] button to switch from those three playing sources. Next time it will automatically memorize its previous mode.

If your phone supports A2DP, you will be able to use function buttons [Play/Pause], [Previous] and [Next] to control the player; for phones which do not support A2DP, please control music through the phone.

a. Aux Out
If you can not find an ideal frequency in your area, and the static not bearable, you will have to use Aux cable and connect KM20 to your vehicle Aux in port; however, some vehicles might not have the 3.5mm Aux port.

b. Aux In
If your device doesn't support Bluetooth, you can use the audio cable and connect your device to KM20 Aux port; then stream audio to car stereo through FM radio.

c. USB Ports
One 5V-2.1A USB charging port to get full charged in short time, and the other one is designed for reading USB files.
