Unfortunately Additionally missing a headphone jack (on the front) and between folders (albums) the USB stick you can unfortunately only change with the corresponding buttons of the remote control.
The biggest shortcoming is that WMA files will not play. Neither from a CD even from a USB stick.
For this reason, I would rather resort to Philips MCM2000 / 12, which has both a headphone jack as well as WMA files reproduces (CD + USB) and this is a bit cheaper.
