Nulaxy Bluetooth FM Transmitter, Enhanced Mic Aux Bluetooth Adapter for Car W 1.8” Color Screen, Car Bluetooth Adapter for Hands-Free Call, QC3.0 Fast Charge, Bass Treble Booster Audio Players-KM20

Amazing value for $24. Just 4 minutes to install because I used aux instead of FM. Used the included aux cable to connect the aux in/out port in this thing to the aux in port in my car, and selected Aux/CD in my car stereo. That's it. No FM settings required. USB charging works. Did not try other sources of music (USB, micro SD) -- don't need them.The only downside is that the mic is weak. In my car, the 12V port is located way down low, over 3 feet from the driver's face. To be heard clearly during a handsfree call, you have two options: (1 undignified) scream at the top of your lungs, and (2 unsafe and bad for your back) lean down to bring your face closer to the 12V port. I choose (1). OK. This is more a problem with the location of the 12V port in my car than with this item. However, if you plan to use this thing in a car with a similar problem, you may want to opt for a model where the display and mic can be mounted away from the 12V port. I think this manufacturer has one like that.

Gave this to my daughter, she was happy when she put it in her car, very easy to use.

First, the good - I had no problem finding a blank FM station without any interfering noise from other stations but have yet to see what happens when I go out of range from the selected FM station. The Bluetooth pairing was fast and easy. The sound is quite good but obviously doesn’t compare with a stock Bluetooth car system. Some reviews have noted that the volume was not loud enough. However, I used the car radio’s volume as the main control in conjunction with the Bluetooth device’s volume control and it was blasting loud. All the buttons and features (and there are many) worked as they should. The bass, treble, and equalizer settings (rock, jazz, classical, etc.) functioned nicely. I had another person call me to test the call sound quality and it was very clear at both ends. Now, here is what I was disappointed in. The instructions need improvement. For example, there is no explanation of what the included fuse is for and where it would go. It comes with an Aux cable, but it does not explain how to use the device with it. It would be good if somehow the device had memory so that it did not go back to the default settings when restarted. The lighted display is good but the dancing bars really have no purpose. Most importantly, none of the function buttons are lit up so at night you cannot see where the buttons are to pick up a call, change songs, pause, etc. It would be better to illuminate the buttons that you need to see rather than the dancing music bars. Also, I discovered that the audio is not stereo. It is mono. I played several songs from my phone that I know have distinct stereo separation and also googled stereo test sites (right and left speaker tests) and confirmed the device did not produce stereo. Overall, the device is very promising and does have some great features, but the lack of stereo and lit function buttons is a problem for me. I did contact Nulaxy customer service about my issues and was very pleased that they responded immediately and are willing to do whatever is needed to satisfy me. So a star added for great customer service!UPDATE - First off, I figured out that, since it is not self-powered like some other Bluetooth adapters, in order to work through the Aux port, it has to be plugged into both the car's cigarette lighter plug AND Aux port in order to get power. Then when I switch to the Aux option on my radio it plays without having to tune to an FM station. Now, the big thing is that I had mentioned that when I played it through an FM station, it would only play in mono and not stereo. But I discovered that when I play it through the Aux port, it does play in stereo. This may be helpful to others who also noted they could not get stereo sound. Unfortunately, my car's Aux port is far back from the cigarette lighter plug, so this requires me to use a much longer Aux cable which is kinda cumbersome and doesn't look very good.

It works perfectly and has great range (like when I have to get out of the van and open or lock a gate. Great bargain.

Enjoy listening to my music while driving. Easy installation. Easy setup. Good audio tuning features that improved the sound quality in my car.Auto connection after the discovery, if you like that.All together a good purchase.

I love everything about this unit but one.It's easy to set up. It connected to my Android phone quickly. I was making phone calls through it within a few minutes of plugging it in.It even controlled Pandora, playing on my phone. Pretty cool.But when I plugged in my USB key, I started having problems. First off--press and hold the "phone" button to access the file menu for the USB. The instructions need to be clearer on that. Once you're in, though, it's easy to navigate.But every time I turn the car off, and turn it back on, it loses its place on the USB key! It starts back up on a particular file--the same file every time--even though that WASN'T the file I was last listening to. Maybe that's okay with music, but I'm trying to listen to an audiobook I ripped from the CD, so I must navigate through a few dozen files to get to my desired file. Plus it loses its place within that file, too.I'm hoping that it's a bug with my particular unit, but I don't know yet. I'll edit this review once I find out.

I like it because it has separate volume button and phone answer buttons. Some Bluetooth has volume button with multiple functions which drives crazy, but this one is easy to use.The bass and terrible buttons works perfect.Only one small issue the general Bluetooth volume is low during phone calls compare to music volume. I wish they could make lauder.

Sound quality was ok, a bit of a hum. Disappointed that when unplugging the unit the entire base (the part that goes into the cigarette lighter) busted and I was unable to re-assemble to working condition.

Este aparato es la mejor inversión que he realizado, no tiene interferencias, el altavoz es de alta calidad, se sincroniza bien. De las mejores cosas que he comprado en Amazon.

I've used FM radio transmitters about 15 years ago, and didn't care much for them, but I needed a solution to get my music onto my car stereo that didn't involve upgrading the entire deck.I was skeptical at first but was blown away by the sound quality and the BASS.My 2005 Camry has really good speakers, and I was shocked by the sound quality of this device.Very easy to use, just pair, select an unused FM station and your good to go.Probably not the best choice for long road trips (you'll be switching stations pretty often I assume) but it's a great package for the price. I'm thrilled. Thank you.

Macht alles, was es soll - Audio (Navi/Musik) kommt gut vom Smartfon an, dass sich Dank der USB Stecker zeitgleich lädt. Freisprech funktioniert auch tadellos. Einrichtung ist ganz einfach.Was ich nicht getestet habe ist Wiedergabe von SD-Karte. Evtl. ist das Abspielen aufgrund des kleinen Displays nicht so einfach... aber das ist Spekulation.Für den kleinen Preis ein wirklich gutes Gerät.

I very rarely write reviews, but for this little gadget, I’ll make an exception.Quick and easy to connect to phones Bluetooth. Quick and easy to connect to radio FM frequency.All audio streamed through car radio, Music, Hands Free Calls and Sat Nav guidance (Google Maps on phone)Sound quality is exceptional for the price point and the noise canceling microphone is amazing. Calls are clearer than on my £500 Apple Play head unit….All in all, an unbelievable price for the functionality. The only minor downside is the build quality, but for the price, that’s to be expected. Having said that, once it’s plugged into a 12v outlet, there’s no need to touch it really.I’ll be buying another for a friend.

Après une semaine d'utilisation.Utilisé sur un Renault Scénic où la prise cigare était trop encastrée:- installation: parfait pour ce véhicule- son de très bonne qualité pour moi, réglage volume, basses, aigus simples.- changement de fréquence: directement avec les (+) et (-) sans avoir à bricoler dans les menus.- Pour ce qui est de Toulouse, et sa périphérie: pas de pb de brouillage ou chevauchement de fréquences. De toute manière ça se change très facilement.
