> put your media on a uPnP server, access it using vlc on a smartphone and then from there send it via bluetooth to the radio using it as a bluetooth speaker.

Hertzshaffnocheinmal! What a contraption. Here's what I want:

1. plug a USB device in that has all my media files on it

2. push "shuffle"

3. push "play"

Like how CD players work. In fact, even steps 2 and 3 should be optional. It should just work when the USB device is plugged in.
