content: Pioneer makes some great auto head units and this is no exception, The unit works and functions flawlessly and looks great. Very simple to operate and there is not a clutter of buttons to add confusion. The USB port is a very handy thing to have but I found that it did not function well when playing music from a jump drive, I think because of the different formats, it locked up and stopped playing. My Ipod worked without any problems at all and was easy to control from the unit. I really think Pioneer makes the Best auto stereo for the money.
