I did a review of the Nulaxy KM18 in the past which had fair marks but fell a little short in the display being too dim and unable to be seen in bright and sunny days. Recently I picked up the Nulaxy KM24 and I am happy to say that this is now my favorite Bluetooth FM Transmitter for cars in almost every way, so let me proceed to tell you what sets this car Bluetooth FM transmitter apart from the many other brands that I reviewed.
First, inside the box you will get the device itself and a 3.5mm audio adapter that can be used to plug in a non-Bluetooth device and output audio letting the transmitter send that audio to the FM station of your choice. When you first take it out of the box you will notice it has a large interface and screen, there is a volume dial and button to pick up and answer calls and there is a CH (Channel) and M (Mode) buttons. It has a previous and next track button as well.
At the end of the gooseneck near where you plug the device into your car outlet port you will find the USB port, and on the left side is a MicroUSB slot for having your mp3 files on a microUSB card if you don’t have a device to connect via Bluetooth. On the right is the 3.5mm aux port for other legacy music devices as well. But what sets this Bluetooth FM Transmitter apart from others is the fact that it does not have auto-play enabled. Which means if you listen to audiobooks like me, you don’t have to worry about your device instantly connecting to and playing your audiobook or music before you even get in the car or sometimes when you start your car but don’t have your radio turned on.
The Nulaxy KM24 also has a power button at the base right above the USB port which allows you to turn off the device when you don’t want it to connect to your phone, or if your car will leave it’s car port on and powering while it is off it is a good way to ensure the device is off and not on while the car is turned off and parked.
Setting the station is easy with the bright and easy to read LCD display that you simply select the channel button and then turn the dial to find the FM band you want to override. If you drive long distances sometimes you can drive into a zone where another radio station overrides or interferes with the FM band of the transmitter but generally it is very strong and only in rare cases does an outside FM signal override the FM transmitter. The volume is sufficient though as with all other brands, the volume on the FM transmitter doesn’t get as loud and you have to compensate by having your car stereo volume turned up which means if you abruptly shutoff your FM Transmitter you can be left with loud static or the radio station it was tuned to before you shut the FM transmitter off.
Overall though, this is by far my favorite FM transmitter and I use it ever weekday when I take the kids to and from school. I sync my Sirius XM iTunes App and my Audible app with it and listen while I wait in the kid pick up lines, or whenever I am out driving for any length of time. The only thing that could be improved is probably adding a 2nd USB port and allowing 2.4A output charging instead of 2.1A output charging.
