SUPER CAR RADIO easy to use, the fact that all have in front (at, usb, cd) is that of happiness. level bluetooh AC connection works well, although sometimes the unit does not recognize my iPhone automatically, but manual connection is fast and easy. small weak point, I find that aesthetically it is a bit limited, my car radio of the same brand that I just replaced after 14 years of good and loyal service, was much more beautiful screen level and lighting. but hey it all and soon forgotten by the many features offered by this one. in short very satisfied with my purchase, it remains only to wish him a long life to me than the last.
