Had a car reciever that couldn't handle the chop and vibration of a marine application. I bought this and my problems were solved. It has a USB connector that you can connect an Iphone, your playlists can be adjusted on the i phone or on the Sony unit. It shows what song is being played. You can change the background lighting to red for night driving. I don't get great AM reception (probably antenna) but everthing else works great. The only downside is the controls arent totally intuitive so you might need to keep a copy of the control manual onboard if you like to tinker with sound settings and use all of the options available. Overall, I am very satisfied.
