One of my absolute best buys
I bought a used car back in February and to my dismay, the aux port was damaged. I (stupidly) did not get the warranty. I was hoping to use the aux port to connect my Amazon Echo or this Bluetooth adapter I had. I was very upset until it hit me - I could just get an FM transmitter. My brother-in-law has one and it works great. I went on Amazon and found this one. I read through a couple of reviews and bought it. It was something of an impulse buy, but I am so glad I did. It works very well - connects to my phone as soon as I power on my car, unlike my Amazon Echo Auto, which I don't miss. I have to turn the sound up on my phone and radio to hear anything but that might just be due to the technology. Once it's at the volume I prefer, music sounds great. For the best results I tuned the transmitter to the end of the FM spectrum and I haven't had to deal with interference with other radio stations. This unit has features that I haven't used yet, such as the aux port on the side, and I just realized that you can put in a micro SD card in it. I will have to try that out as sometimes I don't want to launch the music app on my phone and find something to play. I also love the button you use to answer the phone, and didn't realize you could long-press it for Siri (since I have an iPhone) so I will have to try that out. Initially connecting it to your device is also very easy, as I recently upgraded my phone and had to pair it again. I also love the two charging ports, as you can use it to charge anything else. I used one port to charge my MagSafe charger but I broke that cable by accident. I came back to this listing to buy it for my dad as he needs one, and remembered that I wanted to write a review for this, so here it is. I think I paid $29 for it, and it was worth every penny. It works very well and I love it.

Here's the deal old vs. new?
This product is a good product and it works as it should,in every way but 1!If you compare the older models to the new one then here is the break down!The older model had buttons and they functioned properly and we're designed fairly well one just the old one had a neck on it that was prone to lose stiffness,snap pulling the wire not out but barely stretch and static city!It would also be fair to say the plastic was super thin and it made them rich!There was a legendary sweet invention on the old ones that was so awesome and that is,the know in the middle bottom center that turns the volume up would go so loud and clear!You want bass,you being extra loud #30 on that know was a beast!#30 on the new ones is border line easy listening!Crank it up,I can't!Hear this though about this product as of now it has worked well I have had very little static but there has been some but it happens!It's very well set up and nice digital display!Connects very well with my 3 cars,good,and sterdy case,nice colors,it has been a good product and it could be great if you let me worry about my hearing and let the world crank the volume up to where I think Jimmy Hendrick is right beside me playing the national anthem of the United States of America!I really don't mind saying "Huh" to folks asking me a ?!¡If the volume could be toned up I'd say it's a 5but it's a 4 for me!

Works well, but not really adjustable
Works great! The only issue I have is the gooseneck does not stay where you move it to. It always moves back to its original position so it’s sometimes in the way. But other than that, it’s easy to use and sounds good.

Fits my particular needs near-perfectly
Part of me expected to be disappointed by this, but the idea is just so great I wanted to give it a shot. So far it's performed at or above expectations! I really only use it for one thing, so that's where the 5 stars is coming from...note that things I *don't* use it for may perform much more poorly (perhaps the FM transmitter isn't very strong, etc). I connect my phone to bluetooth, and use an aux cable to connect this device to my car's stereo. It pairs automatically when I turn the car on, and works just as expected. I think what makes me so excited to use this is that it makes it much easier to 1. Change the volume and 2. Skip songs, vs doing those things on my phone or on my car's stereo (I do have a fairly old stereo, but the volume dial is too shallow to grab and twist easily without looking. I can't skip songs on it at all). The display shows my car's battery voltage at startup, which is a nice touch, for an old car like mine that can be valuable info. Oh, and two USB ports are super handy, I use those. Here is my feedback/disclaimers, though. These are things I wish were there but aren't dealbreakers for me, or things I haven't tried at all: * Haven't touched the FM transmitter * Haven't really used any feature beyond what I've described...the SD card reader, the hands-free phone calls, etc. * I wish there was a play/pause button. * I don't think the display shows song info? I thought that was an advertised feature. I mostly use Amazon Music instead of the native music app, maybe that has an impact on this, but it shouldn't. It doesn't bother me, though; I know my songs well enough to not need them displayed. * Number one complaint: it appears that the device sounds (most notably, the "waiting for pairing" and "device paired" notifications, which are spoken) are *not* affected by the relative volume of the device itself!! This to me is a major oversight...what it means is that when I first turn on my car, that voice telling me it's trying to pair is LOUD. I leave my car's stereo volume really high and just allow the volume control on this device to be the governing factor, but when the device audio isn't quieted by the device volume, it's an issue! So, you know, don't let this thing give you a heart attack like it did for me the first few times. It's still an annoyance, heart attack or not. I debated taking a star off for this, it really is a mistake. I'm curious if some kind of settings or something could adjust this (I didn't get any instructions with the device). So, to reiterate, *for my purposes,* this is totally a 5-star item. There are many similar items around, maybe a cheaper one would be just as good, maybe some of these other features don't work very well, maybe this thing won't last too long, but for now, I'm pretty dang happy. It solves a problem I have in a well-done way. Update: it’s been about a year and this device is still doing its job just fine. The loud pairing voice thing is still annoying. I actually think the issue may be that the device has no volume memory, it just resets to a (fairly loud) default every time it’s turned on. I keep my stereo volume a bit lower now, so it’s about right at that default volume. I have to mess with my stereo volume when I want really loud music, but this isn’t very often so the lack of volume memory isn’t a huge deal. Definitely still wish there was a play button, or that it would auto-play your music when it pairs. I’ve used other similar devices since writing this review, and I gotta say, the auto-pairing for this is lightning fast compared to many.

Great for cars that dont have Bluetooth.
This worked really well until I got a car with bluetooth. I should give it away to the next person who needs it. I love the pink and it was easy to use.

I bought this for my teenage son to use in his first car. He had it set up in minutes and loves the convenience of listening to his own music hands free via his phone. Excellent value.

Transmetteur FM/bluetooth qui fait le boulot. Je possède une auto (de marque allemande réputée pour sa qualité et ses innovations) du début des années 2000, avec un combiné radio multi-cd + navigation haut de gamme mais sans BT ni même de prise AUX (alors que le AUX était présent sur ma vielle japonaise des années '90) Ce récepteur FM/ émetteur BT permet de lier mon smartphone à mon auto et de profiter ainsi de ma musique (spotify) et du téléphone main-libre. De plus, via ses commandes, on peut changer le volume du son, les titres joués, les canaux fm, décrocher les appels. Il possède deux entrées USB (dont 1 usb-c) pour la recharge du téléphone. Seul petit bémol, le volume sonore est trop faible de base, il faut pousser le volume de l'auto radio pour une écoute correcte. S'en souvenir avant de passer du BT au CD est primordial si on ne pas subir un arrêt cardiaque :) (1 étoile en moins)

Habe lange gesucht und diverse Produkte probiert und kann dieses für meine Zwecke nur empfehlen. Das Preis Leistungsverhältnis ist völlig okay. Da mein Radio im Auto nicht Bluetooth fähig ist und mein neues Handy keinen Anschluss mehr hat für z.b. dem "AUX" Kabel über das ich vorher die Musik und die Freisprechanlge des Auto Radio's verwenden konnte musste ein "Bluetooth Transmitter " her. Da mein "AUX" Anschluss sowie der benötigte "Zigaretten Anzünder" zwischen dem Fahrer und Beifahrer im Auto angebracht ist fand ich bei diesem Produkt den schwenkbaren Arm und das Display interessant. Das mitgelieferte Kabel ( etwas kurz , aber für meinen gebrauch völlig ausreichend) lässt mich jetzt so wieder die vorzüge des Auto Radio's zwecks Musik hören und telefonieren nutzen können. Die Bedienung für mich als Fahrer sowie für meine Tochter als Beifahrer ist durch den schwenkbaren Arm gut zu bedienen. Die Bluetooth Verbindung hat bis jetzt auch immer super funktioniert. Über den Klang bzw die Ton Qualität kann ich kaum etwas sagen da ich wie gesagt alles über das Auto Radio laufen lasse. Für mich ein gutes Gerät mit leichter Bedienung und Installation.
