Nulaxy Bluetooth Car FM Transmitter Audio Adapter Receiver Wireless Hands Free Car Kit W 1.44 Inch Display (F-Green)......

I used this for my Honda Accord 2003, which has no bluetooth capacity AND had a media system backlight blowout. This is a standout performer in the crowded market of car audio solutions. Its exceptional sound quality, ensuring that music and calls are both crystal clear. Its Bluetooth connectivity is robust, connecting seamlessly to any smartphone without interference or drops. The volume control on the KM18 is precise and intuitive, allowing for easy adjustments to suit your listening preferences. The inclusion of slots for TF/SD cards and USB makes it versatile for all your audio needs. If you're looking for a reliable and high-performing FM transmitter, this offers a superb experience with no compromises.

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.
