Prius 2, nothing fancy on the stereo. What I've noticed is that when I try to navigate music on my iPhone, normally I get the option of HOW to select music (playlist, album, artist, etc.), but once I go down a path, it only lets me go back to the same path previously chosen (e.g., playlist means I only get back to the playlist sub-menu...I can't go back to the master browse menu).
