NOTHING BUT GOOD THINGS TO SAY
This Nulaxy Bluetooth unit actually works really well. I was going to buy Bluetooth speakers to clip onto the visor of my 1997 Land Cruiser, and accidentally ran across these little FM xmitter products. There are many brands and models, but this one had a couple of nice features and seemed to come recommended, so I chose it.I tune it to an FM station that has the least static and no signal at all, and I pre-program that frequency to a pushbutton on my radio. The unit connects via Bluetooth almost instantly when the car is started (and a voice notifies me that it’s connected), and then on a call, telephone conversation audio comes out clear and smooth. Turn it to its max volume and it may not shake the fenders off your car but it’s not bad at all…and that’s on a older truck, too.The only music audio I’ve tried so far is my “Favorites” playlist from a YouTube app. It plays them very nicely. And I can pause them with the multifunction button (and occasionally fast-forward past the ads in between each “track” by turning the multifunction button briefly clockwise…although it sometimes also skips to the entire next track). Fidelity is about as enjoyable as if a radio station was broadcasting the songs.Initially some features weren’t working, until I realized that my dashboard cigar lighter is in a recessed dashboard area that’s too narrow and the dashboard’s plastic was holding the Bluetooth device’s “light” button down. This made a number of features not work properly. So I mounted the Nulaxy device on a small extender “stalk” and it works flawlessly. Navigation audio goes silent during a phone call, but that’s an iPhone thing…and it comes back automatically and quite instantly when the call terminates. Probably again per the iPhone’s own behavior, navigation audio takes precedence over music audio loudness-wise, but the music audio continues playing softly in the background and then comes back to the foreground each time the navigation app stops talking. So I can listen to music while navigating, and it works fine.My strategy if I want to listen to the radio is to listen to whatever station I want…baseball game on AM or whatever…and if a phone call comes in, I just switch the radio quickly to FM and hit the radio’s pre-programmed frequency button, and then I answer the call on the Nulaxy device. If I want to initiate a call, I turn the radio to the FM frequency first and then initiate the call on the phone (by typing or by using Siri commands), then converse via the Bluetooth device.The “dial last number called” quick-double-button-press works too…but only seems to work for the last call that I myself initiated, not the last call that called me and spoke with me. Not a big deal there, and that could be an Apple iPhone thing too, for all I know.I’m not sure if Siri commands work without touching the phone…but of course they still work on the phone itself. About the only small wrinkle, and it’s just the nature of different signal source amplitudes and not the fault of this device, is that FM radio volume must sometimes be turned up a bit to compete with road noise…so in those cases I need to remember that I had turned the radio volume up before I switch back to the baseball game…or I may hear “Beanball!” or “Kill the umpire!” come out of the speakers really loud. (But since I’m yelling those things at the top of my lungs whenever I listen to a ball game anyway, it’s hardly a big deal…)Overall this great little gizmo has it all over my original idea of putting speakers on the visor above my head — so many limitations and complexities are simplified and improved with this approach compared to separate speakers (which would need to be manually turned on, and frequently recharged, and I’d still have to turn off or pause other audio to make them worthwhile at all). This device is a dirt cheap way of adding full-featured completely satisfying Bluetooth connectivity to my nearly-30-year-old Land Cruiser for a whopping $12.47 Black Friday sale price. Would I buy another? C’mon, man, who the heck needs two older Land Cruisers? : )

Great Piece of Equipment
I bought this unit because the reviews were very good and the price was outstanding. Beginning in March of 2026 you can/will be fined if caught using a phone in your hands while driving, even at stoplights. I have an old Honda pickup and decided to give it a try. Could not get it to connect the first time I tried but after that it has been great. Calls received at the touch of a button with no static or noise. Very clear audio. Calls placed by telling Siri to call a number an while dialing pushing the Bluetooth button to transfer to truck speakers. Bluetooth connection almost immediate. Four USB connections that I will never use as I got this for phone only. I honestly don’t know how it could be improved. Highly recommend for anyone needing Bluetooth in an older vehicle. Tested in real life today and it works perfectly placing and receiving calls.

Works great and charged surprisingly fast
Easy to use and works well. It’s no more expensive than a regular charger but lets you Bluetooth phone to radio. I have an 08 Mustang GT with the original shaker 1000 stereo system and it works well with it. Plus it charges really fast too!

Great buy!
This item was perfect. It was super easy to install right out of the box. It came with everything you needed. Would recommend to anybody who has an older car that does not have CarPlay or does not have the option to add one.As long as your car has the cigarette lighter or igniter area, you can play your music and your videos and listening to them on your car speakers.The one thing that I will say, I have noticed, is that when you connect a cable to charge your phone to it the noise level does go down a little bit. The quality of sound drops a bit. Aside from that this is perfect. The buttons are perfectly sized and this item is super functional. Would definitely recommend to anybody.

Colorful and a concert for your trips.
Works like a dream. Took a few tries to find a dead channel to use. Sound is clear, connects automatically, and very sturdy. Cheap for its use.

Beats having to buy a whole new headset for my Porsche
I have a Porsche 997.1 (2006-2008) with a Bose sound system. These are incapable of Apple Car Play. There used to be a third- party fix allowing music and audio navigation directions to be sent to the sound system via a plug-in cable to you phone, but these have been discontinued by the manufacturer and once they wear out are no longer supported by them. So the “fix” is to buy a whole new headset unit for the PCM at about $1600! This little unit, however, does allow those outputs from the phone to be sent to the radio by picking up a Bluetooth output and converting it to a rebroadcast FM signal to a station frequency of your choice. It works great for that purpose. The sound quality is as good as that from any FM station. I have had an issue with having to unplug and replug it in to get the Bluetooth connection to reestablish after parking overnight, but that may be because the cigarette lighter receptacle does not depower when the ignition is shut off. For a short stop it’s okay, but curiously not overnight.

Utilizzato per trasformare una vecchia autoradio di una Fiat Punto in un dispositivo multimediale.Per configurarlo è stato sufficiente cercare una frequenza non utilizzata dalle radio: bisogna scorrere avanti o indietro fino a sentire solamente grattare le casse. Successivamente ho collegato il dispositivo all’accendisigari e ruotato la rotella raggiungendo la stessa stazione.Ci si accorge del suo funzionamento perché le casse smettono di grattare e non riproducono alcun suono. A questo punto non resta che cercare il Nulay con il bluetooth del telefono, associarlo ed il gioco è fatto.Viene rilevato come cuffie e riproduce tutte le app multimediali (spotify, youtube, ecc) oltre ad arrestarle ed avviare la suoneria in caso di chiamata in arrivo, idem in uscita. L’audio è ottimo così come il microfono con riduzione dei rumori. Unico difetto, ma non so se dipenda dall’accendisigari della macchina stessa, in caso di forti dossi questo si spegne e si riaccende, perdendo temporaneamente la connessione ed interrompendo l’audio.Rapporto qualità prezzo davvero ottimo, dal momento che resuscita davvero vecchie autoradio senza dover smontare nulla.Consigliato.

Si sintonizza perfettamente senza nemmeno cercare una stazione con il segnale bianco: anche se c’è una stazione radio di sottofondo la esclude perfettamente e si connette al tel.UsbC sono comodissime, effettivamente in 15-20min di tragitto ho il tel quasi del tutto carico. Lo consiglio

En mi caso, llega a bloquear una emisora y mantener un sonido limpio sin interferencias, pero hemos buscado un dial libre entre dos cadenas de radio por si acaso.Se pueden quitar las luces que por la noche pueden ser algo molestas.Dispongo de un dispositivo de carga rápida a 30W y funciona.
