but Pioneer is better. have this same (Sony) and MVH-160ui. the radio sound is here with the Sony much too lax and hoarse. no matter what you set! must probably be designed ?! usb stick sounds contrast punchier. Pioneer has this "wow" effect also on working speakers - coming here Grar not over ;-( really stupid this is 3 times loud beeping as "anti-theft protection" for the panel. (Which you can not turn off) time was worth a try, but I would not Recommend it.
