Nulaxy KM30 Bluetooth Car Adapter, FM Transmitter with 1.8" Color Screen, Hands-Free Calling Strong Mic, QC3.0 Fast Charging, Treble & Bass Sound Music Player, Wireless Radio Receiver, AUX TF USB

This is really a no frills FM-Bluetooth Transmitter. But there are some faults to this. Let me share the bad then move on to the good. But let me share this major tip. Set the transmitter volume to maximum. While this is a FM-Bluetooth transmitter, it is really is not meant for phone to phone conversation & this product isn't it's strongest feature. Why? Let me explain. When making or receiving a call. You have to press your preset radio station if it's not already chosen to make or receive calls. Especially if you are listening to another preset radio station. It can be annoying to hit that FM Transmitter station. This has happened to me on several occasions. But it'll be repetitive soon. Now several users has mentioned about the feedback noise. While this is true and it stems from the alternator. It's only when you are on a bluetooth call and the radio volume is on a very high setting. However, this does not affect during bluetooth music streaming or using the USB Drive. What I mean is that, when you need to hear someone from the other end of a phone call. The transmitter isn't as strong to produce the sound to all speakers. Even when you have your phone bluetooth volume on maximum. YOu need to turn up the volume from your radio head unit. But again this also depends on your own car speakers as well. So that is one feature that could be improved if the manufacture decides to do so. My other annoyance, is the USB connection. Depending on the cable or USB drive you use. It can be somewhat a tight fit as you can see in my pic. Sure I can buy a right angle cord to charge my phone. But why add more cables to my collection? Now for the USB drive. This can be somewhat a good thing and a bad thing. Upon start up. It can either be recognized or not. Sometimes while playing it'll just go to "unrecognized" for several seconds. Then it comes back again. This product only plays MP3's. No wav, mp4. I cannot comment on AAC or ALAC as I don't have songs in those format. So if you going to bring your music onto a USB Drive. Be sure it's in a format that the KM 30 can play. I haven't tried the SD card feature as of yet. So I will make an update at a later time. The good. The Bluetooth streaming is great. Providing you set your equalizer on your phone correctly or neutral. Most modern Smartphones has an EQ feature. So I suggest you play your favorite song or a song that has a balance of bass, treble and mids. This will ensure that whatever streaming music you use. You will get that sound great. Even with the OEM speakers. Once that is complete. You will want to adjust your stock your radio sound settings. Most stock radio has bass, mids and treble. Set those at neutral and adjust accordingly. Then move onto the KM30 bass and treble and adjust accordingly. This will take some to get the sound you are after from your . Using a USB Drive? Well this all depends on your music library. If you have a library of music on a hard drive, not all music are set a particular bit rate (kbps). I know I don't. I have bit rates ranging from 92kbps to 320kbps. So the best method from my 2 week experience. Again find a music that is really balanced with bass, mids and treble and have a 128kbps. I actually used Metallica- Hollier than Thou and Delinquent Habits - California. Yes I have a wide range of music taste when I cruise. When you play you will have to make adjustments to the bass, mids and treble from your stock radio and from the KM30. So music lovers between normal radio stations, music streaming to music on a USB drive. You will need to find that balance of sound. While this might be a pain. It's so much better than making a phone call. Again this is a no frills FM-Bluetooth Transmitter. This works perfect for older cars once the sound is dialed in correctly. My only suggestion that this product would have an edge over the others. If this could pivot left and right. But that is a small pet peeve on my part. Enjoy! Car 2004 Mazda3 Hatchback.

I recently gifted my husband the NULAXY Bluetooth FM Transmitter, and it has been a fantastic addition to his car! The setup was incredibly easy; he just plugged it into the car's cigarette lighter, and it connected effortlessly to his smartphone via Bluetooth. One of the standout features is the crystal-clear sound quality. Whether he’s listening to his favorite music or taking calls, the audio comes through without any distortion. The built-in microphone picks up his voice clearly, making hands-free calling a breeze. The LCD display is a nice touch, showing the frequency and battery status, and the USB ports provide convenient charging options for his devices. He loves being able to stream his playlists and podcasts directly through the car's stereo system. Overall, the NULAXY Bluetooth FM Transmitter has made his driving experience more enjoyable and connected. It’s user-friendly, reliable, and an excellent value for the price. Highly recommended for anyone looking to upgrade their car audio setup!

I've been using the KM30 in my 2003 Nissan pickup for the past three years, and it has exceeded my expectations. I don't listen to AM/FM radio. Instead, I stream music from YouTube over Bluetooth, and the KM30 has worked flawlessly. Bluetooth connectivity has been reliable, and the audio quality has been excellent. The hands-free calling feature also works great. Whenever I answer a call, the people on the other end can hear me clearly without any issues. I've seen some reviews mentioning alternator whine or electrical interference, but I've never experienced those problems. Very occasionally, if I'm driving through an area with a strong radio station, I might hear a little station bleed-through. However, by choosing one of the more obscure FM frequencies, it's rarely an issue. After nearly three years of daily use, this unit is still performing just as well as it did when I first installed it. Because of its reliability, sound quality, and call performance, I'm upgrading my original 4-star rating to a well-deserved 5 stars.

OMG this is my new favorite toy. I drive a 2005 Toyota Camry. I don’t want to ride with AirPods. This plays on my radio. It’s easy to set up. You can change the stations really easily.

It was very simple to set up the quality of sound is great my old one had static and this one has zero static you can see the screen clear tells you what song is playing you can charge your phone it's a really great device

This transmitter not only sounds great, but it also looks and feels great. The sound quality is as good as your speakers allow it to be. In my case, everything sounds great. I rarely adjust the bass or treble unless I want to mess around with the audio, but it's not necessary. Make sure to use radio-locator or any other website for locating unused radio channels in order to get the best possible performance out of this product's main transmitter feature. The design allows it to be so low profile that it's not an eyesore. Make sure to remove it once you're done though because it does stay on and can slowly drain your car's battery. Another great thing about this product is its durability. I live in California so the sun is not shy to come out. I've left the product in our SUV's front compartment ever since I bought it, which was months ago, and it's still running perfectly. It remembers that it was connected to my phone so I simply plug it in, press play, and head on out. On that note, I would also like to mention that the media controls on this product work for all of the apps I use, such as Spotify, YouTube Music, and Youtube, even when the phone is off. I know that's a common feature, but many products get media controls wrong, not this one. Other things to mention are that the USB ports allow for exceptional charging performance, but I rarely use them so it's not so big a deal to me, but maybe for others. Also, the mic quality as described by people I've called through this product is not the best, but it's good enough to make out what you're saying. It's not a big issue to me because I do not call often when I'm driving, but many others do. The display is great at what it's supposed to do, such as displaying the song name, the song length, the song frequencies, radio station, etc. It's enough information that can be absorbed with a quick glance, do not look at it too long while driving. I cannot comment on the sd card and aux out functionality as I have not used them nor am I planning to because I have no need for them as of now. Overall, this transmitter has great sound quality, great build quality, great features, and a great value. I highly recommend this to anyone looking to add Bluetooth functionality to their car.

READ THE MANUAL AND LEARN FROM MY MISTAKE: Certain types of cars will always supply power to the outlet that this plugs in to, even when the car is off. If your car does that like mine did, then this will slowly kill your battery. I spent a few hundred dollars on trying to find the root of my parasitic drain issue, and on a new battery just to find out that this was the culprit. It does not have an off button, and I need to make sure I unplug it every time I get out of my car. Besides that, the product works well and does what it says it does. The radio mode will pretty much always have a bit of static no matter the station you use, so be aware of that. I use mine with an aux cord plugged in, and with the "aux" mode on my car. The sound quality is great that way. Unfortunately, it doesn't work with the audio controls on my steering wheel this way, so I have to reach around my shifter and hit the tiny buttons to skip forward or go back a song, which can be difficult and cumbersome.

Works great never had any interference and like the voltage meter would buy again

Funciona muy bien, tiene Jack por si quiere micro y sobretodo que es por lo que yo compré se puede prácticamente apagar y no consume nada de batería si tú coche es de los que no cortan la corriente en el cenicero

Absolut genial, im 12V Buchse eingesteckt auf dem radio die Frequenz eingestellt und los giengs. USB Stik mit Musik funktioniert, bluetooth verbindet sich und man kann auch über Kabel an die AUX beim Radio sich verbinden, einfach gesagt tolles Ding, jeder Zeit empfehlenswert. Danke

Had a few of these type of devices over the years and they have all been a bit of a let down. Thought I would give this one a go due to the good reviews and wow, what a difference. I have been using it now for over a month and it has worked flawlessly the entire time. No issues with bt connection but the main positive for me is that I have had no problems with interference and the sound quality for streaming music has been excellent. Then you get the bonus of the nice screen with some info on what's playing and a equaliser. Hands free wise, it always works great and I can be heard clearly by callers. I really am very pleased with this device, worth every penny and saved me having to upgrade the head unit on my car.
