Good morning all, I've recently bought a 2103 c250 amg sports plus saloon and I'm very pleased with it. One thing that I cannot seem to sort out is playing music via the usb. It will not (or I cannot make it) play songs in album order i.e. it seems to play track one from the first album and then follows it with track1 from the second album etc. It does this for music on a stick and ipod. Any help gratefully received.
