KM18 Bluetooth 5.4 Car Adapter with 1.44" Clear Display & Flexible Gooseneck - FM Radio Transmitter & Bluetooth Receiver for Hands-Free Calls, Wireless Music via BT/FM/AUX/TF, USB Car Charger

This is a very nice piece of equipment. I bought it because, neither of my iPod or my vehicle have Bluetooth capability and the car radio does not have an AUX in port. I just plug my classic iPod into the in/out port on the side of this adaptor and tune my car radio into the same FM radio station as the one I set on the adaptor and I have perfect sound. No external electrical interference noises or static. I get just plain excellent sound from the recordings on my iPod, through my car radio. The jacks on both the adaptor and my iPod are 3.5mm. I tried another brand that was supposed to work, but it only had an output jack on the adaptor, so when I plugged the cable into the port, I got nothing. I'm very pleased with this adaptor. I thought I was going to have to buy a new radio for a couple hundred dollars, but this amazing little adaptor saved me from having to do that. It will work if you do have Bluetooth capability. I can't think of any kind of set up this adaptor would not work with. It's well built and feels nice and solid. I would add a video of it working, but I figured I wouldn't be allowed to post it due to copywrite laws. I would love to have everyone listen to how great the sound is through the adaptor and my old time car radio. I am using this in a 2007 Chevy Uplander. I highly recommend this adaptor and this seller. A+++++++ for both!! I had a problem with the fist one I received, but the seller was quick to send out a replacement and now I can listen to my audio books while I drive. Don't be afraid to get one of these if you need to attach an external gadget to your old style car radio. If I need another one, I will be getting the same thing from the same seller. I'm a very happy camper!!

Gets the job done! I have an 03 & didn’t want to pay a lot for some good music. It’s small, but mighty! It’s been good for a couple of years. I have no complaints!

The Nulaxy Wireless In-Car Bluetooth FM Transmitter Radio Adapter is a great product with many benefits and only a few minor setbacks. This product is useful for anybody who needs Bluetooth accessibility in their car and/or does not have an AUX port built into their car for playing music. Throughout this review I hope to inform you on the positives and the negatives so that you can make an informed purchase. The criteria for which I based my judgements on this product include: Compatibility: This product is very compatible with whatever device and vehicle you may be using. Many of my friends have this product, and it works well with all our vehicles and phones. For those who still want to listen to music through this device but don’t have Bluetooth access, there is also an AUX port on the side of the device. These different features make this product useful for many different purposes. Sound Quality: Usually, the sound quality is great and has improved over the years with new models of FM transmitters. Also, the knob on the face of the product allows you to simply turn the volume up or down without messing with the radio. While the sound quality CAN be great, it isn’t necessarily all the time. This is because the device works through a radio station that isn’t being used in your area. Sometimes it picks up interference which causes the sound to be muffled or distorted with other music. I have not had a problem with this, but if you were to take a road trip across the country, you’ll find yourself having to change the station numerous times. Convenience: The Nulaxy is very convenient in many ways. For example, my phone automatically pairs with it the second I start my car making it easy to get in and drive without a hassle. To add on to this, there is a built-in microphone so you can make hands-free calls through this device without distraction Durability: Besides occasional interference with the sound quality, the only other drawback I found was its durability. The product is a bit flimsy and seems as if it can be broken easily if not taken care of properly. I haven’t had problems with this yet, but it is something to take into consideration. Display: The display is clear and serves its general purpose. It tells you which radio station the device is paired to and who’s phone it is connected to. Since there isn’t much else that needs to be displayed, they did a great job at keeping it simple adding no extra confusion. Rating: All in all, the pros outweigh the cons for this device. For only $17.99, you are getting a great product that serves its purpose very well. I give this product a 4/5.

I drive an early-2000's BMW 5 series. It has a factory radio that sounds awesome and a look that is perfectly integrated into the console. But I needed Bluetooth functionality to stream audio. In my other car I installed a $200 radio and while the BT functions worked great, the sound quality and build quality left a lot to be desired and the "look" of the radio was all wrong. I didn't want to do that to my beautiful interior and I wasn't going to spend $800+ on a high-end radio. This little Bluetooth dongle does a fantastic job connecting my new Samsung Galaxy phone to my old car stereo system. It's easy to use, works mostly automatically and is fully configurable to any station on the dial, an important factor for me (or anyone) that lives near an urban area with lots of radio stations. The display is easy to read (though you likely won't need to look at it after you tune it to an empty radio station. The built in charger port has plenty of power to drive my vent-mount Qi charger (which usually don't work with less than 1500mA chargers and better with 2100mA chargers like this one). I listen to MP3s and audiobooks from my phone and both come through rich and sound great on my factory stereo. Some tips: Plug the device ONLY into an ignition controlled power socket, you don't want one that is on when the car is off. Tune the radio until you find a station that is all static and that both of the stations above and below are both static. That really helps keep the signal clear. Then set a radio preset to that station and tune the device to that station too. Once you turn on Bluetooth and sync it with your phone (easier on Android than Apple it would seem) it remembers the connection. You shouldn't have to re-sync it unless your BT security settings are very high. Turn up the media volume on your phone to the very highest before turning up your radio volume. That makes the signal the clearest. The big dial works as a button too, press it once to start/stop (works only with my media player, not my audiobook or podcast players, though that's likely the apps fault). Just be aware that two quick presses of the button will call your last called number. That was embarrassing to me once or twice until I figured it out because the device considers it a double press even if that takes 5 or 6 seconds. Long press to hang up. I haven't tested to ultimate range, but it will still sync the BT from up to 10 feet away. I tested this because I'm buying one for my Mom to use in her RV. I also set up my phone to automatically launch the traffic monitoring and navigation app that starts with "W" so as soon as I start my car it jumps into navigation mode and adjusts the media volume to high and is ready to drive all without having to press any keys.

This was just what I needed in my older car. It took a minute to find a station static free but I found one and got it paired up and music is clear and it works great. I bought a second one for my sister and im excited to gift it to her.

I purchased an 05 vehicle that doesn't have an aux port. This FM transmitter is great. I had music on the vehicles speakers within minutes of opening the box. It's easy as pie. Set the stations to the same frequency on the FM transmitter, and your vehicle's radio, and it's magic to the ears. I love how easy it was to set up, how attractive and compact it is, music quality is amazing, and the price point is unbeatable. It's a no brainer. I definitely recommend to potential buyers.

If you recall back in the 90s there were lots of aftermarket CD player and CD changers designed by Sony, Pioneer, Kenwood and many more that used RF Modulators to transmit through and unused radio station on the FM band. This works the same way, however the RF signal being generated on this unit needs to be stronger. When driving around in the city or any higher populated area where the radio stations would transmit from, you can hear the station (or white noise related to the radio station) on the speakers as you're trying to listen to the content of whatever is connected to this Bluetooth RF device. This makes it not nearly as good as it could be. In some areas were there is less RF energy you only hear the content your play over this device but I would say about 75 percent of the time you can hear noise even if there is nothing playing on this device. One of the most frustrating things about this is that it's avoidable. I'm guessing that the RF power being transmitted from this device to the car radio is likely the max limit the FCC would allow BUT that's not the real problem. The real problem is that the device doesn't go quite lower enough in the FM radio band to get out of the normal range of frequencies that a typical radio station would be on in the first place. The unit only has a range on the FM "dial" between 88.1 Mhz to 107.9Mhz. But most of the older RF modulated devices from the 90s could go down a bit lower to 87.7Mhz where there are no FM radio stations. This makes a huge difference. Since there are usually no stations (or at least no high powered stations) down this low (87.7 to 89.9Mhz) there is little to no noise on the older RF modulated CD changers, etc. but on this you have no choice to be deal with the noise mixing with your played content. Lets than ideal and I'm sure the folks who made it isn't from the US so they may not know that the USA's FM radio band goes lower than what this unit is designed for. My radio in my car goes down to 87.7Mhz. This low on the radio band there is nothing there. If this unit could be programmed down this low the noise wouldn't be a factor.

Easy to setup, no issues finding a station that works, and connects to the phone every time! Ive always felt FM transmitters are hit and miss as far as how well they work or of they work at all. I was pleasantly surprised by this one. Used in 07 Highlander, plays audio great with no issues. I do not use this for phone calls so cannot rate based on call clarity or connections.
