I should have listened to the other reviews that said the quality was poor before spending $11 on this app. You are much better off connecting using a USB cable or aux cable for sound quality. If your car doesnt support Bluetooth music streaming then there is probably a reason. Quality is fine for phone calls using my cars Bluetooth but not for music. This app really doesnt add any value, and its not even more convenient than plugging in with a cable.
