Nulaxy Bluetooth Car FM Transmitter Audio Adapter Receiver Wireless Handsfree Voltmeter Car Kit TF Card AUX 1.44 Display - KM18 Golden

*edit!* The company responded to my support request over the weekend, and has been trying to help me resolve this. They responded by email before this was published, I believe the delay was time zone related, so I took that as a good sign. I will update when I've received the new unit*2nd update: their customer service is stellar, they relentlessly worked on making this right. My original unit was a now discontinued version of the km28, and I still don't know if the km18 I received was defective or just didn't play nice with the SD card from my old unit, but they sent me the new version of the km28 and everything is working fine now.They tried to troubleshoot the km18 with me beforehand, and even sent me another km18 due to a misunderstanding before sending me the km28, which is working perfectly. This is a pretty specific use case, but be aware that although they use the same card, file formats, and everything else, you may or may not have issues with an SD card formatted for an older unit in this device, though I suspect it was simply a defective unit.With Nulaxy, if you have a problem, I'd highly encourage going through their customer service rather than just returning it, they're thorough and prompt with addressing the issue, and more than fair about resolving it, I haven't had customer service this easy to work with on anything else I can think of except maybe my $1200 chainsaw.Original review:I've been using nulaxy products since 2018, and I bought 2 of these to replace a km28 (no longer manufactured) because it has the same features I required (SD card slot, multiple music format support, Bluetooth, and a gooseneck.) The old unit still works but there's constant crackling and buzzing coming from it, and that's fine, it had a long life.These new units do not work properly despite having the same SD card requirements and formatting. I plugged one into the car, and inserted the old SD card, other than re-pairing my phone and changing the radio frequency it began playing immediately.Unfortunately, the new unit I tested froze constantly where nothing worked, it has to be unplugged to reset, and when it does work it only plays the first 15-20 seconds of each song before skipping to the next one. I reached out to nulaxy support via email and chat, but have received no response and my chat said I was number one in que for over 20 minutes, with an estimated 1 minute wait time, so I gave up. I was hoping they would be able to help me troubleshoot the issue and offer a solution rather than return them, because I have been happy with both units I have previously owned by them, but I've never tried to get customer service from them before and I am disappointed. I will give them a few days to reply before I will have to return these.I did put my micro SD card back into the original km28 unit to confirm it was working properly, and everything is fine on the old unit aside from the previous complaints after years of use, so I know it's not an issue with the card.I did not test playing Bluetooth from my phone, because I need both features to work properly for different purposes, but I do not recommend this unit, whatever is causing the issues I'm experiencing makes it unusable.

Absolutely love! This Is my second time purchasing and by far my favorite Bluetooth transmitter from them. I used to have it in a nissan, unfortunately that car got destroyed. And my transmitter was still intact after someone rammed me. I bought the transmitter again after I got my new car a honda. It can get extremely loud. So if you're young or just love blasting music this is it! For volume you want to make sure your phone is turned all the way up. Then turn up the volume on the Bluetooth transmitter. Then the radio volume! It also provides ways to skip songs on the transmitter, without having to touch you're phone. The perfect channel for no static and clear audio is 88.1, at least for me. It may not look very modern but like I stated the quality and sound is so good. Ill take quality over looks any day. Please dont listen to closely to negative reviews, nor good reviews. Undertand that you can purchase, and try it out. Remember if you dont like it, YOU CAN RETURN IT. Returning has always been an option. I personally have tried their other designs. Remember reviews are a persons preference. Just because something isnt for me, doesnt mean you wont like it. I personally didnt like the other transmitters. So I returned, and I was refunded. THIS ONE I ABSOLUTELY ADORE! And omg dont get me started on the customer service. Their customer service is amazing! They reached out to me first! They were so kind and even offered to send me a different design to test out. So please be kind to them, but be honest to help them improve. Or even if you have any suggestions provide them, you never know they may surprise you.

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.
