So I am sitting in the dealer lot today picking up my CTS and
making adjustments with the radio.

The XM sounds like complete garbage on this system. I plug
in my brand-new 160GB iPod via the supplied cable. I select AUX
and find that the PLAYLISTS and all my songs come up as expected.

However, upon selecting a song, I get the name on the screen but
nothing plays. Select another song, same thing.

So I try unplugging my iPod thinking maybe the volume has to be
up on the iPod or some other setting. I check the plugs. I have the
serial connection on the bottom and the earphone (RCA) plug on
the top of the iPod.

What am I missing here that is preventing audio from playing?
