I have already pulled a couple searches on this without any answer to my question. I know about the IPOD, but my question is about the USB connection. It says that it will use any storag device, now does this include a hard drive? I ask because I can get an external hard drive for cheaper then an IPOD and would prefer this (more GB for the $$). And if I can do this does the hard drive need any special programs on it? Or can I just load all my MP3s on it and use my radio controls??
