Review on Criacr Bluetooth FM Transmitter for Car: Wireless Radio Adapter with Dual USB Ports & Hands-Free Calling – Grey by Tyrell Christmas

Definitely an upgrade for eg the AUX cable. Music runs without problems, on the phone normally. Every now and then I have to repeat myself. I would give this 5 stars BUT I can't continue without it interfering with normal radio station playback. It's great when you're plugged in, but when I want to listen to the radio I unplug it a bit so it doesn't get power and my radios are fine again. For the price it's worth it and I recommend this product.
