I have installed the device for several months in the car and I am very happy with it. It is a Mediaceiver, so no mechanical components such as CD / DVD drive, but everything else gets leaked digital only radio, either an external hard drive, USB stick, laptop or smartphone. Connections abound, audio / video playback either analog (Cinch) or digital (USB) or Bluetooth A2DP. Operation is intuitive, touch screen available and the big volume knob is fail, quick to use and therefore more meaningful than any volume keys. A truly well-designed product. Absolute recommendation.
