Product works great and just as expected! Easy to use and Bluetooth connects easily without hassle! Sound quality places great through the radio of your car!

This is simply TOO COOL and functional for words. First it is extremely intuitive (didn't even have to read the manual...just looked at the quick start guide which showed what each button does). And, as important, it is much safer to use, while driving, versus fumbling around on your smartphone or iPod/iPad, when playing music on your car stereo (more on that, below). I have several older model vehicles which do not have Bluetooth and this solves a huge problem, elegantly and simply.When I am driving on the highway, I use my iPad Air 2 for music, with all of my iTunes playlists loaded onto it. Getting that music into my car's sound system was not possible, before I found this wonderful device. First I plug the Nulaxy into the car's accessory plug-in, which turns it on automatically. Then, I turn on the iPad (or any smartphone with Bluetooth) and ask for it to "find" and "pair" with other devices, at which time it finds the Nulaxy automatically (when the Nulaxy is plugged in and "on"). Then open iTunes or other music player on your device and start up a song. Then go to the Nulaxy and use the upper two buttons above the "dial knob", to go up or down the FM station selections to find a clear signal where you can hear the music playing from your device. And you are done with that "launch" step.Here is where this device is so much safer to use than fumbling with your music player device.A) If you want to mute, for an incoming call, you simply push the illuminated blue button in the center of the dial, which automatically pauses the song that is playing on your device, to allow silence for taking a phone call or other reasons needing silence. You can also put the phone call into your car stereo system with a couple of button pushes. And you can recall the last number dialed with a couple of button pushes on the center dial. And when you are done, just push the center button again and it goes back to playing music where you left off.B) Push the forward and reverse buttons without taking your eyes off the road, to advance to the next song, or go back.C) Turn up the volume by spinning the round dial (just like you would on your car's stereo dash controls). Or, alternately, use the volume up or down buttons, which flank the round dial that does the same thing. I use the round dial instead of the car's volume control because I first turn up my music player device to close to 100% for the best sound transmission and then use the Nulaxy volume control to go up or down. I found this to be the best mix for optimum sound. Although, if desired, you can still use your car's audio system dials for volume. Multiple options for the safest mode for your needs.D) And a great feature which covers all the bases...let's say you have a music player that does not have Bluetooth (maybe an old ipod, or a cassette player or whatever) and you want to get the music from your device onto your car audio system using the Nulaxy. The Nulaxy has a 3.5mm stereo mini plug port on the side of the unit that allows you to run a simple stereo cord from the headphone jack on your player, into the Nulaxy, which then transmits the signal to an FM station on your car stereo. Good engineering to be the most user friendly and feature rich.E) There is also a TF Card port on the side of the unit, which allows you to use a TF Card or Micro SD card in the Nulaxy. I have not used this feature so I can't comment on its usefulness.F) And the last feature worth mentioning is that there is a USB charging port on the back side of the part that plugs into the accessory outlet of your car (cigarette lighter style port). So you can plug your device into this to keep it charged while driving and using the Nulaxy. Great for extended periods in which you want to conserve battery on your smartphone or player. CAUTION though, which most people may already know. You probably do not want to use your cigarette lighter port (if you have a dual port..one for accessories and one for a cigarette lighter), because if you plug anything into a cigarette lighter port, for an extended time, it will cause that port to overheat and possibly cause damage to the wiring and/or your device plug. I made that mistake at one time and plugged something into the cigarette lighter to charge, while I was using the alternate accessory port for the Nulaxy. After about 20 minutes, I reached up to control something on the radio panel and noticed that entire area of my dashboard felt very hot to the touch and would have probably short circuited or started a fire, had I not discovered the over heating by accident. So be careful with this potential hazard.All in all this is a fantastic little unit, which works extremely well and is very user friendly with all of the features one could possible think of, for mobile music linked to your car stereo. I plan on buying a second one to keep in my powerboat and for use in other vehicles.

After a decade of driving the first car my family ever had with any kind of AUX input, I'm back to driving a vehicle with nothing but a radio and CD player. I got very used to listening to podcasts and doing hands-free calls over bluetooth and listening to the tinny phone speaker while driving just wasn't cutting it.I used to use FM transmitters AGES ago and they were always junky. This one is much better, a much more polished and premium product than those crummy ones I had in the past. That said, it's still an FM transmitter and this technology as a whole is what it is.Having the DC plug built-in AND having a USB charging port built-in is very convenient. I saw another review mention that it stays powered on even when their car was turned off. I've experienced this, too, in my vehicle, both with this device and the USB charger I've been using until now. I'm no expert, but my car has 2 cigarette lighter ports - one on the dash where they always are, and another inside the center console thingy. The one on the dash will keep things that are plugged into it powered on when the car is off, but the one in the center console powers the device off when the car is turned off. I have no idea if this is a common thing in cars or not, but maybe it'll be something to try for anyone else having the same issue.The bluetooth connection on this works really well. It pairs with my phone quickly and the connection is pretty stable on that end. The screen is easy to read, the volume dial works well and so on. Tuning to an empty station can be a little tedious, since you have to click, click, click one at a time, but I mean, that's just how it goes. My car's radio only tunes based on .2 (i.e., it goes from 88.7 to 88.9 for example) while this device tunes based on .1 (88.7, 88.8, 88.9, etc). I'm not sure that means anything but it's something I noted. But it's nice that you can try almost any frequency on the FM radio dial; the first FM transmitter I got back in high school just had a toggle switch that only gave you 4 options!All that said, the connection and sound and experience vary, as they always do with these devices. It seems like it was rougher the first week I had this and I've been having better luck since then. There's usually a little crackle or hiss, especially when the sound is a little punchier (ie, when a podcast host is putting extra emphasis at the end of their sentences). One day I noticed that I was sometimes getting more static when I was stepping on the brake than not. One day I consistently got mostly garbled signal.For whatever reason I've had a smoother experience the past week. And maybe it does better when I'm driving around closer to my house than when I go across town. I'm no expert on the science behind it; this is all just anecdotal observations and I can't draw any real conclusions.But that's kind of the thing with these devices. They work by transmitting to your radio, and if your area doesn't have any nice, clean, unused frequencies it'll have to work over a strong, existing signal (I guess?). You'll have to play around with it to find one that works well enough and you have to understand that sometimes the experience will be more finicky and disappointing than other times and that's just how it's going to be.As for the hands-free phone function, I haven't tried it out yet. I did also miss that from my previous vehicle, but the need has not come up to test it yet. Given that the control to pick up is on the device and not a button on my steering wheel, I expect it will be slightly less convenient to reach to pick up, depending on where your DC outlet is.I spoke kind of harshly about this, but honestly I'm not dissatisfied. Especially for this price; it's a solidly-built device that interacts with your phone very well. (Oh, the charging port is great, too - charges just as fast as my dedicated USB car charger, if not faster. It's not just a junky afterthought). But again, you have to have realistic expectations of the sound quality you're going to get.I think it's worth giving a try. For the most part, it's a better experience listening to podcasts through my car speakers with sometimes iffy sound quality, but it's comfortable enough to listen to more often than not. It's never going to be anywhere near as clean a sound as a more direct connection to your vehicle's sound system, but if you don't have any other options I think it's worth a try.I've been using it consistently since I got it a few weeks ago. There has been one trip where things got garbled enough for me to turn it off, a few more where the sound was obnoxious but listenable, and more where it's ranged from minor-hisses-and-crackles to no noticeable issues. I'm satisfied with the purchase, and at this price I feel like it's worth the money.

LOVE this product. 2004 BMW Convertible with NO AUX PLUG. This works like a charm. YES I had to change the Channel a couple of times to find the PERFECT Signal. Sound Quality is AWESOME. YES I did Adjust the volume on my phone and I adjusted the Volume on the Unit to find the Sweet spot, then I could leave those alone and just use the cars volume to get great crystal clear sound. Easy Setup took Under a minute. Phone calls are clear and with Noise cancellation even on the highway people could hear me well.
