Let me guess... you got an SR+?
That comes with the partial premium interior. Which doesnt include real time traffic info, or streaming media. And it only shows you the quickest route (that I know of anyways) based on your choices for navigation in the car menu.
It DOES take into account traffic when you use navigation, you just don't see it (although you might get a message popup saying routing isnt using traffic info, if you loose the signal temporarily).
As for sound/music, you have FM radio, pairing a phone for media over bluetooth, and I've also heard it will popup with a USB option if a USB stick with music on it is inserted.
