The menu was slightly revised compared to the KD-R422. While there Performers folder followed by the respective Album folders are displayed continuously, the KD-R452E uses a multi-directory structure. By pressing the menu button all the songs of the current folder are displayed. Per Back button to go up one level and can, for example, scroll through all the albums. All artists are displayed in turn by back button.
This requires a properly-run music library with folders for artists and albums. For the correct order, you can put two-digit track numbers before the filename, for example with the freeware Mp3tag. I think there is even a JVC software for it.
The only drawback: the knob I found the KD-R422 beautiful.
