I have a 2012 grand touring with nav and RSES, and I get no song info with either of our iPhone 4s running the latest iOS 5 version. There's a thread on Apple's discussion forums where a guy has a theory it's a problem with the Bluetooth unit, and he's working with his dealer to get it resolved (look for posts by Blarnson). My plan is to keep an eye on that, and if he gets it resolved, take it to my dealer and get them to fix it.
