I have a 2013 XTS. I have been tagging songs off XM radio. Each time I tag a song I get a message informing me that the song will transfer once an iPod is plugged in. I bought a brand new iPod Nano yesterday from Best Buy. I set it up at home, plugged it into the XTS on the way to work today and nothing happened. No songs transferred--nothing. So I am officially confused as to how this is supposed to work. Any help would be appreciated.
