it work out of the box right away - make sure you use the right USB port and right app. Also there's something in the setting to use the correct app by default. Can't remember the new out of the two bundled with the radioPlayed around with it for about 45min. Everything works flawlessly but can't get CarPlay to connect. Kinda sucks. Im happy that got blutooth tethering working so now the weather app and others that need internet work. Carplay is nice but not having it isn't a deal killer. Anyone know of a decent aftermarket microphone? I have mine on the A piller close to my head and ppl say they can barely understand me.
