Review on 🚗 Enhance Your Car Audio Experience with Bluetooth FM Transmitter:Wireless Car Radio Adapter, MP3 Music Player Car Kit with Hands-Free Calling, QC3.0 Charge, LED Backlit, TF Card/USB Connectivity - Compatible with All Smartphones Audio Players by Rahul Schatz

Cute and small, it only took a few minutes to install - just connect the iPhone to Bluetooth, tune in to the desired FM station frequency and start streaming music takes a minute. It's nice to see a regular volume control on the device and the music quality is excellent. I also tested hands-free, the call quality was good, both for me and for the person on the other end of the line. It's great to see how a small device can be so useful and make a powerful (old) car audio system useful in this day and age.
