Are the newer models not coming with hard drives? I've loaded all my music on the storage space in the 730N. I still have factory the CD/DVD player in mine, which makes ripping actual CDs easy. The wife's Dart has a CD / USB / SD setup in the arm rest, she uses the SD card as it's quick and easy to edit what is on it. I don't pay for Sirius since I listen to pandora and Iheartradio via the phone...only a few satellite stations I like anyway.
