    I had seen these bluetooth type of devices before but never really thought about how MUCH MORE convenient it would be to be able not worry about cords and just enter my car…wait a couple of seconds…hear the device say “Paired” and be up and running with whatever I have going on my iPhone.I would suggest that you do an internet search for blank FM frequency/channels in your area because you’ll need to find one in order to get the best audio quality. I experimented around to see if higher frequency channels did better, etc. but didn’t find anything conclusive other than you need a really blank frequency.Also…remember that when you travel…as you head into other larger metropolises…you probably will have to change stations…and that’s not fun if you didn’t plan ahead…especially in a big city!Overall…I’m really glad I bought this and it works great!

    I can keep the introduction simple – I highly recommend this device if you are looking for an FM transmitter. I am absolutely impressed with this device. I have owned a number of different FM transmitters in the past, with very mixed results. I was shocked at how easy it was to set this one up. I originally did not intend to use the Bluetooth functionality in my car, as it has Bluetooth for making phone calls that I use regularly. As it turned out, it was easier to get both Bluetooth connections to play together than it was to mess around with an AUX cable all the time.One thing I found particularly surprising about the overall functionality was its clarity of transmission. For the fun of it, I connected my transmitter to the power port inside the center console between the front seats. Even enclosed in that space, there is no static, no difficulty connecting my phone, and no loss of sound quality. If I was looking to use the buttons on the device, this would be a terribly inconvenient place to connect it, but it works nonetheless.Changing channels, advancing to a new track, re-initiating Bluetooth pairing are all easy to use functions on the unit. Just press a button and magic happens. It has been a long time since I had one of these that was so easy to use and have work.

    UPDATE TO 5 STARS:When I had received this, I had the issue stated below, which I was upset about and almost returned and tried another brand. Although now I tend to believe that I had just gotten a dysfunctional one. About a day after I had posted my review about this issue, I had gotten an email from Nulaxy, letting me know that they apologize for the issue I was having and offered me the plus version, which had an on and off button. I was already very pleased that they had cared so much about how I felt about the product I received and really tried to make me satisfied, which they had most definitely done. The new item came in the mail shortly after I accepted the offer and now I am extremely happy with my device I received, and they had given me another warranty plan for the new device. Their customer service and willingness to helps make them deserve the five stars, and I would most definitely do business with them again because I know I will be taken care of. Thank you Nulaxy, and a thank you directly to Sunny for making things right and making me over satisfied. 5 stars.PAST REVIEW:DOESN’T FIT IN MY CIGARETTE LIGHTER WITHOUT HAVING TO SHOVE IT IN AND OUT!! I’m not sure if mine was just a bad one or if they are all like that but I would rather not have to pull the transmitter with all of my strength just to take it out of the cigarette lighter.

    This thing works so well and everyone I meet is always impressed. My brother, mother, and fiance all have one of their own because its just so easy to use! Automatically pairs when I get in the car and the physical buttons are great so I can skip songs without looking down from the road. Makes me look at my phone way less while driving. There’s also the wired aux port so friends who don’t use bluetooth can still connect. As long as you find a good empty radio channel, I’ve always had high quality audio. One sort of annoying thing is that when you travel long distance the radio stations fade in and out and do change their broadcasting frequency. So if you drive like an hour away you will likely start to hear some static and may need to find another channel, but that’s just the nature of the technology and not the fault of this product at all!

    I wish I would have discovered this product sooner! My son was the one who told me about these bluetooth radio tuners, and, I admit – I didn’t think he knew what he was talking about as he was describing it. However, he was persistent, and said some of his friends had devices like these in their older cars, so I did a little research and was happy to discover that the kid really was correct in describing these devices! Connecting my iPhone to this was a snap, and now I can easily play whatever I want to listen to in my minivan – despite the fact that it has no USB ports or functioning CD player. I leave this plugged in in my electric port in the van, and it turns on and connects to m,y phone, automatically, when I turn on the vehicle. It has made listing to music and podcasts in my van much more enjoyable and I just love this bit of technology. The only thing that doesn’t work well is trying to use the microphone feature on my phone while it is connected to this device. My speech is very rarely recognized and transcribed properly, so if I want to use any sort of talk-to-text or similar function on my phone while driving, I unplug this device while doing so. Aside from that minor quibble, I am really pleased with this device and would highly recommend it to any smart phone user who drives a vehicle without any sort of USB play-through capability in their car audio system.

    Purchased for my wife to use in her Yaris because it doesn’t have any Bluetooth. She loves it. It automatically connects with her Galaxy S7 phone and starts playing immediately when she turns on the engine.Good quality construction – doesn’t feel “cheap” – the cigarette lighter part is firm inside the cigarette hole and holds up very well – the neck is strong and doesn’t flop all over the place, which is what she was dreading before purchasing it. The buttons are soft and easy to press. The screen is not too bright – just bright enough to read during daylight or nighttime.Good Bluetooth connections – she hasn’t had a drop Bluetooth connection yet and she uses it every day to drive to work and back (30+-minutes commute to and from work).FM signals are strong and clear, not much static as compared to older FM transmitting devices, however, she mostly uses the 3.5mm cord method instead.You can also plug in a MicroSD card if you don’ t have a dedicated Bluetooth device, like a cell phone, where it plays the music from. Its built-in music player is good too and very responsive. The tracks change very fast.Clarity of music through FM is good but if you can use the 3.5mm jack to plug into the car stereo, she advises doing that instead. The clarity is much better through the 3.5mm headset and much louder too. The singing tones (I think that’s mid-tones??) are much clearer and the highs are crisper in comparison to using the FM method.Phone calls on this unit are good, but not the best. Though the Yaris is not the best car to insulate road noise – she’s had some complaints of not able to hear her or the traffic is too loud and sounds like she’s sitting in the middle of the freeway. Good news is that the caller’s voice is loud and clear since it’s from all speakers in the car.Her favorite feature is the volume nob, as it has a click each time it turns to adjust the volume – she doesn’t have to look to change volumes and keeps her eyes on the road.Although there is an LCD screen that shows the song titles, time, etc., she hardly notices it.Blue LCD lights are not too bright at night time when she drives. She says it’s like a little blue light illuminating from the center console where she has it placed.Overall, this transmitter is quite impressive for its price and what it does. It did exactly what my wife needed, which was to play her songs from her phone via Bluetooth – with the music still being very clear – along with being able to pick up phone calls while driving to and from work.

    First thinks first. I was very critical of this product when I ordered it but I have to say I was very pleasantly surprised at the way it works. My problem was my car has no Bluetooth but it does have a aux port so I had to plug my phone in every time I got in and needed a better way to use my phone in the car. Pros. It’s very easy to set up and pair with your phone with Bluetooth. It Will work with Siri on your iPhone. You can set it up with empty fm station on your radio or use the aux cord that’s provided with the unit if you have a aux port. I can even have Siri open my amazon music app and then tell Alexa to play my amazon music which I thought was a cool extra. You can control your music with voice or skip or go back with the buttons on the unit. Hands free calling, music and navigation. What more can I say. Now for the cons. I have read some reviews about some static when using fm station. It does not have a power button to turn this unit off so if your power source does not turn off when you shut off your car you will have to unplug it. It is lightweight and made of plastic. It will only pair 1 phone at a time. All in all I have had a great experience with this unit. I plug it to my aux port and it powers off when I shut off the car and auto pairs when I start it up. And for the price it can’t be beat. I would recommend this little unit to anyone wanting to go hands free.

    Device does precisely what it says it should do and then some!This bluetooth to digital FM radio signal adaptor works to deliver the best quality audio I have heard yet on my SUV stereo and is literally superior to the sound quality and ability to play louder, than I get playing an HDCD directly on the CD player that is part of the Lexus Stereo that came with my GX470 and is not the upgraded audio system or even a high end name brand system–yet the sound quality of the FM radio receiver when its receiving the digital radio signal from the Nulaxy (running on frequency 89.7 -just randomly chosen low frequency on FM dial with no stations on adjacent FM bands) into the factory installed AM/FM radio on my 2004 Lexus GX470. the sterep system performs better than I have ever heard it sound using either the FM radio to play local FM radio stations with good signals, or even an HDCD directly played on the stereo systems built in CD player! This was the first digital signal receiver I have owned on a factory installed car radio where you can see the stations handle and even the song name on the digital receiver’s LCD display so it is a decent radio system but its not a higher end or after market AM/FM car audio system so I was not expecting it to sound much better than the earphone jack to cassette adaptor that got lost or broken before I bought this adaptor. But BOY WAS I SURPRISED when I cranked the volume on the car radio dial it delivered such a clear signal without any audible distortion or noise in the lower bass, mid-range or even the upper frequencies of rock tunes I played from my Amazon Music or iTunes library!I was totally surprised it sounded this good…. was expecting a slightly dirty/noisy signal similar to the sound using the headphone jack and the cassette adaptor I bought maybe 4 years ago after wanting to connect my 1st iPhone or iPod to the car radio. Of course cassette adaptors are one of the worst methods to transmit music from your phone to your radio but I did not think Bluetooth over FM signal would be anything great, though in theory it should have been bettter as there should only be noise added across the radio interface–but not in this setup!… It seems that bluetooth to FM is a very clean interface and its not any different than connection from my iPhone into newer car with native bluetooth entertainment system that is integrated with the iPhone for playing iTunes or telephone connections without need to use any adaptor.FWIW- I set my iPhone volume towards the top of dial. I also set the Amazon Music app or the Tunes Appplication volume within the app to near the top as well. This was the signal that is gettting to the radio is already near the high end of volume and so any amplification to the volume that is needed is done with my radio’s volume dial, keeps it simpler had I needed to adjust for better quality I could have lowered the volume on the iPhone and on iTunes or Amazon Music player btut it sounded perfect using just the higher settings in the phone and app. WHen I carnked the car radio volume-magic-it sounds like my BOSE speaker or other high end stereo receiver in my home stereo in quality…that never was case on this car stereo before–normally never crank the car audio as it buzzes or crackles on high volume bass or sounded tinnny on the treble or mid-range setting it up higher…now it just sounds like I have good car stereo aand a high end car stereo/radio! Thank you Nulaxy! I never knew I owned a good car stereo until I used your adaptor..taught me a lesson about griping about bluetooth or car stereo …. MY SUV came with an after market DVD player ofr movies for kids on long trips etc. and that system used an FM modulator to connect the DVD player’s sound to the Lexus FM receiver-and it used low frequency on FM dial as well-but it never sounded particularly good to me, it was just acceptable as the sound for a DVD or CD…so again–this device is far superior in transmitting its FM signal to the 10 year old DVD system installed by the car dealer as an aftermarket DVD player.Thank you Nulaxy! “Saul Goodman” :0)

    I drive an 08 Nissan Sentra that has bluetooth but not really lol I’ve tried out SO many different kinds of bluetooth transmitters and have never found one that automatically connects to my phone, UNTIL NOW! This little thing has been great because it not only autoconnects to your phone, but charges it, you can answer calls, and change the radio station to fit your needs easily. It even gives you information on your car battery. I always unplug it though whenever I’m not in my car just because I don’t like having things constantly plugged in, but everytime I plug it back in and phone’s bluetooth is on, it automatically pairs. I’m in heaven with this thing. It looks great, isn’t flimsy, screen is easily readable, and I can take it with me and use it in any car if I want (think rental cars!). The only downside is that it’s playing through the radio, so the bass and just overall sound isn’t up to par with using a dongle and just plugging my phone in. If it was the same quality, I would use this 100% of the time, but I do alternate plugging in and bluetoothing it.

    You will not regret the $15. I know this because one of two things will happen when you buy this.1) You will receive a product identical to mine and you will be pleased.2) You will receive a faulty product and Nulaxy will send you a new one.This transmitter fits perfectly in all the cigarette lighters I have tried it in, and with the neck flexibility it is fully customizable. In my car this means I can face it up towards myself and the screen is easy to navigate. The sound quality is phenomenal when playing through bluetooth or with an aux cord (it wasn’t perfect at first but I gave it a little time to warm up and now it’s great). The sound quality is a little less good for talking over the phone but I think that’s my phone’s fault, not the transmitter.Another great feature is that once you connect your phone with bluetooth, it will be connected automatically next time you’re in the car, and very quickly too.Some reviews have complained that there is no on/off button. This seems stupid to me. If you turn the car on, the transmitter turns on; and if you turn the car off, there is no power being supplied to the transmitter and it turns off.This is where the research ended for me, and it should for you too. This device is flawless, and the company behind it is wonderful.
