Nulaxy Bluetooth FM Transmitter, Wireless Radio Adapter Hands-Free Car Kit with 1.8 Inch Display, QC 3.0 & 5V/2.4A, USB Drive & SD Card Aux in & Out

I started looking at the basic FM units from another MFG. My biggest concern was that the Aux Jack could be used as on output, to bypass the FM. There were numerous answers to that question, but the wording of the answers left much doubt as to their knowledge or intent. I would like to thank Shilo, for a very detailed review and comparison between this and another MFG. Basically identical. I also finally found a couple of reviews that gave me confidence that the Aux Jack really was dual purpose. Input from music source or output to radio in Aux Jack. I am not concerned about using it with a phone, other than possibly to play music, so have not tried the Bluetooth. I wanted to bypass the FM, in case there was too much interference on the FM stations. I tried both the Aux Jack, as on output to the radios Aux In Jack, and the FM. Both sounded quite good to me. I tried them with the car off and running. Both ways, there was no static or unwanted noise. I like that I can use the FM when I want, and if things get noisy, I can just hit the Mode button, on the radio, and switch to Aux In and no more noise. For my purpose, this just pushed all the right buttons. Other things I like are: 1. My cigarette lighter turns off, with the ignition, and when I turn on the ignition, it starts playing from the song that it left off at. 2. A push of the Mode button, allows you to search for songs by folder. 3. The center knob allows for easy volume adjustment. 4. My lighter jack is close to my right leg, but there is still enough adjustment to keep it clear and out of the way. 5. The power plug went into the Cigarette Socket relatively easy and seams stable. 6. The display is large, bright, colorful, and shows quite a bit of info. 7. The documentation is simple, but gets most of the info across clearly. 8. Came with a nice card, with information to register for the 18 month warranty. They really did their homework when the designed this. I only tried it this afternoon, and will update my review later if anything comes up. I think anyone would be satisfied with the features and quality, so far, of this product. It is nice, when you buy something, and it just works.P.S. As to the Aux Jack, I have not tried it as on input, but I suspect that if the input, on the transmitter, is set to Aux, that it will electronically switch over to an input circuit. I will verify this, at some point, and update my review. I will also add a picture when I get a 90 degree audio cable, and micro SD or very small USB card.This is an update on the free device offer. When I registered the warranty, they offered me a free Amazon gift card, for the full price 0f one of 3 specific devices, if I ordered it from Amazon. I got the NX09 Nulaxy Bluetooth FM Transmitter for Car, and just received the gift card for the full price. I can use this in one of my other vehicles. So far I am very happy with the unit in this review. The FF button is very convenient, and I can use it without even taking my eyes off of the road. I have it mounted vertically with the FF button on top, and a 90 degree Aux cable on the bottom. This keeps the cable and the unit away from my leg while driving. One other thing, if you have files, in multiple directories, it seems to play a few from one directory, then a few from the next, and so on. I do not know if there is any mode to keep it in the same directory, or whether this is a bug, but I do not mind it.

Update Feb. 1, 2019: I found that finding stations that have no broadcast work the best for bluetooth pairing. I've had a couple of incidents where the matched channels with broadcasts were static ridden. If the station has just a bit of a hiss, it's a good match for the bluetooth band and I was less likely to have any interference. Redial the channels on both the M29 and radio to match. Make sure not to dial to an existing radio broadcast.Jan. 26, 2019: First of all, this is a pretty addition to my vehicle. I have a 2005 Rav4 SUV and I recently replaced a radio with my daughter. I thought about adding bluetooth that way through as regular installation, but the price of, I think it's called a GTA bluetooth adapter was cost prohibitive for me, so I started researching bluetooth for older vehicles w/o bluetooth. I found this updated version around $25. Wow. Is this worth it. We paired the bluetooth channel with an identical radio channel. For us, 94.5 FM. Turned the bluetooth off on my phone, then back on, and a soft woman's voice says we're connected to bluetooth. I ask Google to open Amazon Prime Music. We find 90's Music and the car floods with amazing sound and clarity. I only had to adjust the radio volume up a bit. I haven't used the usb port for a music source yet, but both my daughter and I were able to keep our phones charged while we played music. I wish there were 2 C charging inputs as her phone, a Samsung Galaxy 7, didn't keep a charge while she played games on her phone. My Samsung Galaxy 9+ kept its charge while using the one C input. Also, it was a little bit tough getting in and out of the lighter input. The materials are light, but not flimsy. Overall, I love this bluetooth. It looks sharp as it's keeping beat with the music, the sound quality was remarkable, no static was ever experienced, even while we charged our phones. I love the hands free calling. I can listen to IHeart radio on Wase and Wase lowers the volume so I can hear directions, then resumes the music volume. Calls are clear and amazing also. I use Google for calling hands free as well. I haven't used one other feature that I'm going to look into as well that I think starts with a T? Anyway, for $25, this is the bomb. Super easy to use. Just read the instructions, they're pretty straightforward. Turn your phone bluetooth off, then on, after you pair the radio channel with the bluetooth channel. Pick M29 on your phone's bluetooth selections. Iheart, and Amazon, which is all I've tried to date because they have such a great selection of music, is really all you may need. The music sounds amazing. I cannot say enough about that. Hope these instructions here as well help too. I think you're going to LOVE this M29.

Tanken är god men kvaliteten på sändningen ok - inte mer.

One of the best product for those who are not having Aux port in their car stereo but it is bit costly. Overall product is best in his performance.

Muy buena calidad de sonido en stereo, muchas opciones, muy rápida y fácil conexión bluetooth, muy bien la navegación por carpetas de pendrive usb.En mi humilde opinión tan solo le falta un botón de encendido y apagado, si lo tuviera seria el aparato perfecto, pues al no tenerlo has de ir poniéndolo y quitándolo de la toma del encendedor, y se hace engorroso en ocasiones.

The media could not be loaded. Ero indeciso se investire centinaia di euro in uno stereo nuovo per la mia chilometratissima volvo sprovvista di Bluetooth ed Aux, stavo impazzendo ad ascoltare sempre gli stessi cd o la radio nonostante io abbia ormai da anni un abbonamento a Spotify, finché non mi sono imbattuto in questo aggeggio, per quello che costa è perfetto, la musica si sente bene, installarlo è facilissimo, non è integrato con i comandi al volante ma i suoi tasti sono comodissimi, si forse per le chiamate non è il top, ma sfido chiunque a pretendere la perfezione per queste cifre!!

Y es que tuve que esperar ¡DOS MALDITOS MESES! jejeje para recibir el Nulaxy KM29 Bluetooth FM transmisor; pero créanme la calidad del transmisor es ¡excelente! ¡en todos los sentidos!... tienen que adquirirlo.:D
