I purchased my AirFly Pro 2 with the hope it would allow me to connect my iPhone, which has all of my music on it, wirelessly to my car's audio system. My car is 17 years old. It doesn't have built-in Bluetooth, but it does have an Aux port. For many years, I have been connecting my iPhone to the Aux port by using an audio cable. When that connect started acting up a few months ago, I decided to try using a Bluetooth adapter to connect my iPhone to the car's sound system. I considered cheaper Bluetooth adapters, but their reviews often mentioned poor sound quality; so, I decided to spring for the AirFly Pro 2. I'm glad I did. Setup was easy, the adapter worked perfectly, and the sound is great.
