Review: NOTHING BUT GOOD THINGS TO SAY - This Nulaxy Bluetooth unit actually works really well. I was going to buy Bluetooth speakers to clip onto the visor of my 1997 Land Cruiser, and accidentally ran across these little FM xmitter products. There are many brands and models, but this one had a couple of nice features and seemed to come recommended, so I chose it. I tune it to an FM station that has the least static and no signal at all, and I pre-program that frequency to a pushbutton on my radio. The unit connects via Bluetooth almost instantly when the car is started (and a voice notifies me that it's connected), and then on a call, telephone conversation audio comes out clear and smooth. Turn it to its max volume and it may not shake the fenders off your car but it's not bad at all...and that's on a older truck, too. The only music audio I've tried so far is my "Favorites" playlist from a YouTube app. It plays them very nicely. And I can pause them with the multifunction button (and occasionally fast-forward past the ads in between each "track" by turning the multifunction button briefly clockwise...although it sometimes also skips to the entire next track). Fidelity is about as enjoyable as if a radio station was broadcasting the songs. Initially some features weren't working, until I realized that my dashboard cigar lighter is in a recessed dashboard area that's too narrow and the dashboard's plastic was holding the Bluetooth device's "light" button down. This made a number of features not work properly. So I mounted the Nulaxy device on a small extender "stalk" and it works flawlessly. Navigation audio goes silent during a phone call, but that's an iPhone thing…and it comes back automatically and quite instantly when the call terminates. Probably again per the iPhone's own behavior, navigation audio takes precedence over music audio loudness-wise, but the music audio continues playing softly in the background and then comes back to the foreground each time the navigation app stops talking. So I can listen to music while navigating, and it works fine. My strategy if I want to listen to the radio is to listen to whatever station I want...baseball game on AM or whatever...and if a phone call comes in, I just switch the radio quickly to FM and hit the radio's pre-programmed frequency button, and then I answer the call on the Nulaxy device. If I want to initiate a call, I turn the radio to the FM frequency first and then initiate the call on the phone (by typing or by using Siri commands), then converse via the Bluetooth device. The "dial last number called" quick-double-button-press works too...but only seems to work for the last call that I myself initiated, not the last call that called me and spoke with me. Not a big deal there, and that could be an Apple iPhone thing too, for all I know. I'm not sure if Siri commands work without touching the phone...but of course they still work on the phone itself. About the only small wrinkle, and it's just the nature of different signal source amplitudes and not the fault of this device, is that FM radio volume must sometimes be turned up a bit to compete with road noise...so in those cases I need to remember that I had turned the radio volume up before I switch back to the baseball game...or I may hear "Beanball!" or "Kill the umpire!" come out of the speakers really loud. (But since I'm yelling those things at the top of my lungs whenever I listen to a ball game anyway, it's hardly a big deal...) Overall this great little gizmo has it all over my original idea of putting speakers on the visor above my head -- so many limitations and complexities are simplified and improved with this approach compared to separate speakers (which would need to be manually turned on, and frequently recharged, and I'd still have to turn off or pause other audio to make them worthwhile at all). This device is a dirt cheap way of adding full-featured completely satisfying Bluetooth connectivity to my nearly-30-year-old Land Cruiser for a whopping $12.47 Black Friday sale price. Would I buy another? C'mon, man, who the heck needs two older Land Cruisers? : )
Review: Perfect Gift for Everyday Driving Convenience - I bought this car Bluetooth adapter as a gift for my husband, and it turned out to be a great choice. He didn’t have a way to charge his phone or listen to music in his car, and this solved both problems easily. The sound quality is clear, the connection is stable, and the fast charging works really well. He also likes the LED lights and how easy it is to use while driving. Overall, a very practical and reliable product—highly recommended!

## Questions & Answers

**Q: What is the size of the plug-in connector, and which car models is it compatible with?**
A: Sizes: Diameter 24mm with spring clip, Depth 57mm This size fits most car models but is unsuitable for sockets in recessed areas like glove boxes. After use, hold the car’s socket with one hand and pull out the charger with the other to avoid damage.

**Q: How can I avoid or reduce noise?**
A: For best sound quality, set the car audio volume below 50% before connecting your phone. Then, connect to the FM frequency & Bluetooth. Adjust the phone & BC91 volume first. If it's still too low, adjust the car audio system to reach the ideal level.

**Q: How do I match & switch frequencies?**
A: Turn on car radio to blank FM frequency. Set the BC91 to the same frequency as the car radio. Long-press the BC91 rotate button until frequency flashes. Turn clockwise to increase, counter-clockwise to decrease.

**Q: The device isn't working/power isn't responding/display isn't showing/car audio isn't receiving sound/unable to play?**
A: 1) Ensure that the FM transmitter is on. 2) Verify the transmission frequency of the FM transmitter matches the frequency of the car's radio. 3) Unplug the BC91 and connect it again. 4) Confirm the files on the USB device are supported by the BC91.

**Q: How to pair the FM transmitter with your phone via Bluetooth?**
A: Plug BC91 into car cigarette lighter socket to power on. Enable your phone's Bluetooth is on. Then search for 'BC91 and select 'connect'. Once connected, you can start playing music, using navigation, or making hands-free calls.

### ⭐⭐⭐⭐⭐ Works so well I thought I upgraded to a subwoofer WOW. THIS PRODUCT ROCKS LITERALLY.
*by D***R on March 21, 2026*

Ok so I've tried alot of these off brand bluetooth receiver's and this one by far takes the gold medal out of all of them. The ports are great and the fast charging actually does charge very fast. The sound quality is pretty good but could use a little bit more treble but I love it because this tiny thing comes with a built in amplifier for bass and it actually works amazing. I have a Harmon-Kardon audio system in my mini cooper that came stock in this particular model mini cooper and I knew I could push the speakers alot more in terms of bass but I expected this Nulaxy product to either not have the bass amplifier work or barely work and I was wrong it blasts so much more bass into my speakers that I thought I had an actual 10 inch subwoofer in the back hahaha thanks Nulaxy for making such a great product and further more for the excellent price to match. Great job.
