This is a great device, especially for the money. It works flawlessly. Set the FM frequency, pair it once with your phone, and from then on when you power up the device, ie, start the car, it says, "Waiting for pairing" and as soon as it finds your phone, it says, "Paired". I use it mostly for streaming my prime music bc the little one loves to jam. It's hands free phone handling works well, too. Music stops playing, phone rings through car speakers. When you answer phone, your voice is picked up by a mic in the device and your caller comes over the speakers... no feedback issues. My only issue with it which my husband had no issues figuring it out was how to change the chanel to one that worked with my radio. it was hard to figure out but i gave him the instructions and he managed to figure it out so that is why i am giving it a 4 star review.
