Why do you even need to do this anyway? How critical is it to listen to radio tunes while selecting MP3 tunes? Why not just listen to MP3 tunes while selecting other MP3 tunes?

Oh, I know the answer to this one...
My parents were in my car one day, and my dad was asking about the empeg since I'd been raving about it for ages. It was set on radio at the time, so I wanted to change to the player and demo the visuals etc. Of course, the last track I had been listening to was Metallica's cover of "So What" by the Anti-Nowhere League! Just about the least parent-friendly track on my empeg!!
There was a moment's embarrassed silence while I figured out what to do. For some reason that I have never been able to fathom, mute doesn't work in radio mode on my Mk1, so I had to turn the volume right down, change to player mode, select a track, and turn the volume back up...
That is the one time I can remember that I really wished I could still queue up an mp3 while listening to the radio
