I have noticed neither, but I have noticed that my media will be completely off when I get back in the car. It used to be Slacker and my station was remembered when I would come back to the car, even if music wasn't queued up yet and Slacker needed to download a song. Now I get in my car in the mornings and evenings and the "Now Playing" tab is grayed out and I must go through the menus to select a station again.
