The update that is being talked about here is for 2012 vehicles only and will not work on a 2011. As of right now there is not an update that will make streaming audio quality better. However this does depend on the issues that you are having. Does the streaming audio work currently? Have you had the update for the 2011 vehicles done (I am assuming yours is a 2011 because that what is listed in your information box, top left of your post).
