The KDR-401 JVC: Sonically: Good Operation: relatively time-consuming (eg set EQ comes SMS typing the same), but many possible settings ("crossover" [Bass / Treble / Middle] on the radio set) USB: This is my personal point of criticism. Because the "browse" the folder is too long compared to other manufacturers and the Radio assigns not alphabetically but randomly.
In the end, a great radio for the money, especially for those who prefer the original Cd's.
