Review: A very good update for an older Thunderbird! - 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!
Review: No static! - I had very low expectations for an FM transmitter. They have all had static or FM interference as you drive around. This one did not! Connected easily the first time and every time. Music was clear and static free. Even worked pretty well for speakerphone calls. You will want to unplug it from power when you leave the car so it will drop the bluetooth connection.

### ⭐⭐⭐⭐ Great Product
*by A***R on March 6, 2026*

Works flawlessly for my audiobooks and music. While the sound quality is not as good as phone-to-bluetooth, it is as good as any FM station, and I am not willing to replace my car stereo. The phone-call function is no go. The mic on the device can't overcome the cabin sound in my 2008 Forester. It works. But terrible. I just switch to my earbuds for calls. This is the only reason I did not give it 5 stars. If it were just a Bluetooth broadcaster without attempting to do what it can not do well (phone calls), it would have received 5 stars. IMO, they should just remove the call-mic function.
