Figured for seventeen bucks I'd try it. Worked first time and now I actually use my car speakers.
Over 8,000 Cars That Sound Right Again
Bluetooth FM Transmitter
Didn't know it lit up like that
The lights cycle through colors and I can actually find the ports at night now.
Perfect for older cars
If you're driving something from 2010 or earlier with no Bluetooth, this is the fix. I've got a 2012 Civic and it works exactly like it should. My buddy's still using the aux cord like it's 2008.
Wasn't sure it'd work in my truck
I had a transmitter like five years ago and it was all static, so I figured they all sucked. This one actually connects clean if you find an empty station down low on the dial. Glad I gave it another shot.
Haven't touched the CD player
I drive a 2012 Civic with 140k on it and the aux stopped working last year. Used to just deal with the phone in the cupholder but my girlfriend got sick of repeating herself when I was on speaker. Plugged this in, tuned to 88.1, paired it once and now everything just comes through. Navigation, calls, playlists, all of it. The CD player hasn't moved in three weeks.
Sounds way better than I expected
I thought it'd be all static like the cheap one I had before but I found an empty station at 88.1 and it actually sounds clear.
Drives DoorDash twelve hours, charges three
I do delivery seven days a week and my phone's always dying mid-shift. This thing keeps my phone going, my backup battery topped off, and my passenger's phone charged when I'm running rideshare nights. Navigation comes through clear and I can take orders without pulling over.
Didn't know I needed the extra ports
Bought it for the music part but the three USB ports turned out to be the thing I use most. My phone stays charged, my girlfriend's phone stays charged, and I still have a port left over. Way better than fighting over the one socket.
If you drive an older car, get this
I drive a 2012 Accord with 160k on it and I'm keeping it until the wheels fall off. No aux, no Bluetooth, just FM and a CD player I never use. This thing paired in like thirty seconds and now my whole Spotify library plays through the actual speakers instead of my phone sitting in the cupholder. If you're driving something paid off and you're not dropping money on a new stereo, this is the answer.
Bought it after my aux cord died for the third time
I kept saying I'd just buy another cable and never did, phone was just sitting there playing to nobody. Saw this for seventeen bucks and figured worst case I'm out lunch money.
Your Phone Has Everything. Your Stereo Has Nothing to Play.
This Plugs In and Gives It a Signal to Pick Up.
The car is paid off, the radio works, and the only thing missing is a way to get your phone's audio into the system.
So your music plays out of the phone in the cupholder and your navigation prompts come through at half the volume of the road noise around you.
The aux port gave out or was never there. A new head unit costs three hundred dollars and a morning at the stereo shop. You are not doing that.
This transmitter plugs into the 12V socket, pairs to your phone once, and sends everything to an empty FM frequency your factory stereo picks up. Music, podcasts, turn-by-turn directions, phone calls. All of it through the car speakers, controlled from raised buttons on the transmitter you can work without looking down.
Bluetooth to FM. Plays through your factory radio.
Three charging ports. Takes one socket, returns three.
7-color light ring or steady single color.
Why FM Transmitters Beat Aux Cables and New Stereos
Aux cables break at the plug and quit mid-drive. New stereos cost what a month of car insurance costs and need an installer. FM transmitters pair to your phone once, play through the speakers you already have, and add three charging ports where you had one socket. The stereo stays factory, the phone stays in your pocket, and the music comes through clear if you tune to an empty station instead of the crowded default one everybody leaves it on.

The Bluetooth FM Transmitter sends phone audio to an empty FM station your car radio tunes to. Sound quality depends on finding a genuinely clear frequency, down at the low end of the dial, not the crowded default the unit ships on. Tune it right and it sounds fine. Skip that step and you get static.
Your Phone Has Everything. Your Stereo Has Nothing.
Plug it into the 12V socket. Pair your phone once. Tune your FM radio to a clear station at the low end of the dial, match the frequency on the transmitter's display, and everything on your phone comes through the car speakers. Music, navigation, calls. No aux cable fraying in the console, no Bluetooth upgrade wired behind the dash, no new head unit that costs more than the car is worth.
The call button, track skip, and mode knob are raised and separated so you find them without looking. Three charging ports on it, two USB-A and one USB-C, so you get back more capacity than the single socket it takes. The display cycles between your car's voltage and the FM frequency it is broadcasting on. Ring lighting runs seven colors on a breathing cycle or holds on one steady if you want it quiet at night.
How It Connects
1
Plug Into 12V Socket
Takes the lighter socket. Gives you three charging ports back, two USB-A and one USB-C, so you gain capacity instead of losing it.
2
Pair Your Phone Once
Bluetooth pairing, one time. After that it reconnects the moment you start the car. Music, calls, navigation, all automatic.
3
Tune Radio to Match
Find an empty FM station, down at the low end of the dial. Set the transmitter to the same number. Audio plays through your speakers.
Not an upgrade kit. A plug that makes it work.
The car is paid off and you are not putting money into it. This plugs into the lighter socket and pairs once. Tune the radio to an empty station at the low end of the dial, set the transmitter to match, and the audio comes through clear. Takes two minutes, works every time after that.

Bluetooth FM Transmitter Questions
How does the sound quality compare to playing music off my phone speaker?
+
Night and day. Your audio runs through the car speakers instead of out of a phone in the cupholder, so you get full stereo at whatever volume you set. The key is tuning to a genuinely empty FM station, down at the low end of the dial, and setting the transmitter to match. Skip that step and you will hear static from crowded frequencies. Do it once and the sound is clean.
I had one of these before and got nothing but static. What makes this one different?
+
The difference is not the transmitter, it is the frequency. Every FM transmitter defaults to the same crowded band, which is why they all sound terrible out of the box. Tune your radio to a station with actual silence, no talk, no hiss, 88.1 to 89.9, set this to the same number, and the static disappears. The display shows you exactly what frequency it is broadcasting on so you always know what to dial in.
My charger is already in the 12V socket. Where does my phone plug in?
+
This has three charging ports built into it, two USB-A and one USB-C, so you end up with more places to plug in than the single socket it takes. A phone, a passenger's phone, and earbuds can all charge at the same time.
Does my car need an aux jack or anything besides the FM radio?
+
No. If your car has a working FM radio and a 12V or 24V socket, this works. Nothing plugs into the phone and nothing gets wired in behind the dash. It pairs to your phone once over Bluetooth, broadcasts to an empty FM frequency, and your factory stereo picks it up.
What do I get besides being able to play music through the speakers?
+
Music, podcasts, navigation prompts, and calls all come through the car speakers instead of out of your phone. A single button answers and ends calls, raised controls let you skip tracks by feel without looking down, and the three charging ports mean everything stays powered. The display cycles between your battery voltage and the FM frequency so you always know what is tuned in.
