Syncwire Bluetooth 5.4 Car Adapter 38W FM Transmitter Hands Free Calls

Ok. I admit my visceral reaction to first spotting this adapter was, “huh, that seems a little expensive.” After review and initial use, I’ve changed my mind about that. I am prejudiced about cheap Chinese knockoff products. I expected this to be another. It is not. Fit, finish, and feel are quite high. Functionality and placement are well thought through, especially for such a small footprint/volume. Ultimately I needed it to do what I bought it for — to be a good interface to play music from my phone, not to look fancy. How did it do? These are initial impressions- I’ll update later if warranted after a bit of road use. But for now — setup was effortless. It locked into the vacant channel and between this device and my car's radio the channel went silent of any static. Engine was running - no alternator whine. Bluetooth pairing took 5 seconds. Audio was clear and loud. No hiss/distortion at “too loud” radio volume, so verdict is — success. I was not even looking for or even noticed on Amazon the hands-free phone function and built in microphone. Great feature since holding a device is a no go (legally here and functionally — car has standard transmission). I cannot review that here yet. Having started my driving during “AM Radio and one center dash speaker” days - I’m used to the dance on road trips of stations coming and going. So I’m sure same will be for this system if on the road and a nearing station on the selected frequency gets strong enough to walk on the selected frequency — welcome back to early 2000’s when XM came into existence. Ya just have to pull over and tune a new unused channel once in awhile - no biggie. So far — I’m impressed with this item. Oh! And a three year warranty?!? What product these days comes with the three year warranty??? That’s impressive too.

My RX8 only has an AM/FM radio with CD & cassette drives, and an option to connect to a mini-disc player which I never purchased. The CDs sounded fairly good, but when I got an iPhone 16 Pro Max I had room enough room to load my entire library of CDs on the iPhone but wanted a better way to play music on the Bose sound system in the car. I bought a Syncwire 5.4 to see if and how I could integrate it into my car's sound system. It turned out to be pretty easy and is easy to use while driving and the price of the Syncwire is very reasonable. I put an attachment on my center console that holds the iPhone 16, plugged the Syncwire into the cigarette lighter and found an unused frequency on the FM channel and selected that channel on the Syncwire. I set one of the FM preset buttons on the Bose to that frequency I'd selected on the Syncwire so that I could listen to other FM station presets on the Bose so I have access to both the Bose and Syncwire by just using the presets, and the CD player still works normally, but I doubt I'll ever use it again. The iPhone and Syncwire connect with Blutooth, the iPhone is in a spring loaded cradle, and can be powered directly from the Syncwire with a short USB-C to USB-C cable to keep the iPhone battery charged, but because the Syncwire runs a little hot I put a second charger in the cigarette lighter socket in the console between the driver and the front passenger seat console and ran a USB-C to USB-C charger cable from the charger to the iPhone. So now I can use the iPhone's Music app to pick the songs or playlists of my choice and play them through the Bose sound system and keep the iPhone charged up on long drives and never listen to the same song twice or repeat songs from the iPhone's screen, easily remove my iPhone and Syncwire when not in use and I am extremely pleased with the results. I bought a spare Syncwire (just in case). [The iPhone in the photo looks larger than it appears because it's closer to the camera lens].

It’s good, I don’t know if it’s my truck but on certain places the static becomes too much and I have tried multiple stations. I had other products similar to these and this would scan the radio stations to see which one is the best. The features are fine, the bass light is a bit annoying but can be turned off. The bass booster works great. The phone call button is useful but haven’t tested the microphone, you can press once this button to play or pause your music but can skip the song with 2 taps which is something I wish it had It’s really easy to connect to it and delay is almost none. Good value for the money

My 2002 T-Bird now has functioning Bluetooth and access to my iPhone thanks to this little device. The Syncwire was easy to install and link to my phone and is working quite nicely as I had hoped it would. Choosing a proper FM station as described in the tiny instructions. That was critical as one station with even minimal station interference was not optimal. Also, I had originally picked an FM frequency above 101 and it appears the device does not connect to stations above 100...at least my device did not. The directions did not mention that aspect of the process. I do wish the phone and other buttons were on top of the unit: when the device is installed with the screen properly oriented, the buttons are on the underside where they are not readily accessible. Another reason I selected this model was for its visual simplicity. It's simple round design fits in nicely with my vehicle's instrumentation. So far, this was a great choice!

I bought this for my 2008 Miata which has the Bose system with a multi-cd system that no longer works. I actually got the Syncwire Bluetooth Transmitter as a stop gap while I shopped for a new car stereo unit. To my surprise, this Syncwire Transmitter works great! Much better than I expected! I’m thinking now of just keeping the Bose unit and using the Syncwire Transmitter and using my iPhone for the music source. Great value, no connectivity issues, music sounds great.

This product does work but has some downsides that should be noted. First and most importantly, when you take a call and your phone is connected to this device it will go through the microphone on the Syncwire. This leads to very poor call quality and requires me to switch my phone off the device so the other person can hear me. Also, I'm not sure if it's just how it connects to my phone but it will always max out my volume initially. I have been startled many times by this. Furthermore, if I have the volume too high on my phone the sound quality drops off considerably. Some positives are that it was easy to set up, that my phone connects well to it, and that it was relatively cheap. Overall, this product does it's job but there are many areas for improvement.

I use it everyday at work to run my fan, charge my phone and watch.

There are a lot of reviews saying the light is annoying, but I personally love it. I'm old-school and I like inside colored lights, lighted accessories, and old cars. Maybe their cigarette lighter is too close to them. Mine is off to the right down low,so I don't think it's gonna bother me at all at night. I think it's kind of fun. I haven't noticed it getting hot yet but I plan to only use it for Bluetooth and not charging my phone at the same time. I have another charging port inside my console that can be used for phones. When I first hooked it up, one song had a lot of static despite picking the best station. Went out and tried it again today and I'm not noticing it and I've got good bass and there's also a base setting on this device which is pretty cool. One thing that needs to be changed is, I want the phone setting on top so that makes the radio station upside down. They need to reverse it. See picture. Hopefully it will last longer than some reviews said. Perhaps they had just bad luck. I hope. So far, I really like it and was glad to find for my 2006 Nissan Pathfinder.

Brought as a gift, receiver delighted.. Works well. Excellent quality. Would buy again if needed to

Love the quality of clear sound ..very practical as we can move it from car to car

Works fine, connects fast, but just don't expect great sound as if connected to a direct source. No fault of the unit, just the way it is.For 30 bucks it is worth it.

It is sturdy and well made. This works great for getting your vast music library off your mobile phone onto your cars sound system though there is some audio quality lose due to transmitting the music from the phone via bluetooth and then converting it to an fm transmission. I would recommend using the bass boost to help counteract the audio loss and the sound of the road. It happily charges two devices fast via the usb sockets so no excuse with having your phone battery run flat. It has controls for adjusting volume, pause/play and changing tracks forward and back. It also has functions to work as a handsfree device to answer the phone but since I dont use the phone at all while driving I have not tested this. If I had any criticism for this it would have to be: 1. It has an always on pulsating light which is dim during the day but depending on the car maybe distracting to the driver while driving at night. 2. it should switch controls for volume and track forward./back. Currently you can just twiddle the dial and it changes the volume but if you press the play button twice and then twiddle the dial it will change track. This is pointless as realistically speaking you would use the big volume knob on the radio to change the volume after setting the FM transmitters volume to a balanced volume with the in car radio and cd player. This would make it alot easier to play and change tracks while driving as double pressing the play button is destracting. It doesn't really bother me as I remove all songs from the playlist before I set off. All in all I think its a great bit of kit with a few shortcomings but well worth the purchase.

It's simple and straightforward, works as advertised. It feels well built and sturdy. It's a good size to just leave in the dash all the time, doesn't get in the way or distract. I like the rotating ring for FM frequency selection and volume. The colour pulses to the music, and can be turned off. It remembers the last FM frequency you tuned it to, and displays it on startup. The USB-A and USB-C power ports are a nice addition, but I haven't tested them yet. It has no amplifier, so the onboard volume control is really just a volume reduction. I just leave it at max and use the car stereo volume. Not so great: No buttons to skip to next/previous song. I guess I can learn to live with that. The "extra bass" button works but resulting sound is muffled and muddy. Don't bother. The hands-free phone connectivity works, but the mic is very weak. Callers can barely hear me in the car with the engine off. It's unusable when driving, especially on the highway. There's more difference than I expected between low and high FM frequencies. Empty spots in the 88-90 Mhz range sound noticeably worse than empty spots in the 104-107 Mhz range, for same car / same phone / same song. Radio stations at the low end of FM come in clear, this device from a foot away - not so much. And finally, it's quieter than I expected. With transmitter volume and phone volume at max (and onscreen "hearing damage" warnings), I have to turn the car stereo up much more than I would for a radio station. Strong local station might need 40-50% car stereo volume at highway speed, but this transmitter needs 75% or more to get the same actual volume. Same phone in our other vehicle with native BT doesn't have this volume difference.
