My friend just got a RCA H100A MP3 player. I currently have an IPod Shuffle. I though that ITunes would work for both player. I had her bring her RCA H100A MPS over but I can not get anything to down load to it. Is there other software that I need? Should she of had a CD with her MPS player? Confused, please help me get my Itunes onto here RCA H100A. Thanks!
