Hi,

when on the ipod play screen (the one with artist, playlist etc.) push down on your big button it will shuffle your songs .

 

I've only had my car for a week so I could be wrong, but after choosing my artist, I shuffled.I was surprised to find that it did not shuffle my just artist's songs, it shuffled all the tracks on my pod. What if I'm just interested in shuffling just the artist I've chosen?
