“It works great and sounds great. Super easy to use. Just plug in and connect your Bluetooth. The fm connect ability is a nice option if your car doesn’t have an aux setting. It was a decent price. It’s fairly small so it doesn’t distract from your driving.”
“I had a Bluetooth 4.2 transmitter that was doing just fine, but just bendable neck had broke, allowing the face/head of the transmitter to spin and not be able to hold in place. It was a ‘BF20’ model. Nothing wrong with it, I broke it on accident I guess… well, maybe it was a little weak. Anyways”

Frequently Asked Questions
Q: How do car FM transmitters work?

Q: Are FM transmitters legal to use?
A: Yes, they are completely legal in the United States and most countries. They use low power that doesn’t interfere with licensed radio stations. Just make sure yours is certified by the FCC.
Q: How do I find the best FM frequency?
A: Turn on your transmitter and scan your car radio for static. Pick a frequency with the least interference, usually between 88.1 and 107.9. Avoid numbers used by local radio stations. Many transmitters have auto-scan features to find clear channels.

A: Absolutely. Most models include USB ports for charging. The JOYROOM even has three ports so you can charge multiple devices at once while streaming music.
