I have the Sandisk 2.0 GB mp3 player. I just purchase 1.0 GB extra for the expansion. I am not sure how to get songs loaded on the removable memory and how to get it configured so that the mp3 player recognizes and talks to it to get the music. I believe the directions said to switch to USB mode, but the only modes I have in the settings is "Rhapsody" and "Play for Sure". Any help with this would be appreciated. Thanks
