Trying to play music from my iphone 5s using a USB cord. It used to play pandora, soundcloud, etc. perfectly, now it says "NO MUSIC" when I plug it in. Has this happened to anyone else? I've researched a little bit and saw it may have to do with the type of file music is saved as, but it used to work and now it doesn't. Still under warranty so I will take it to Lexus if no one has come across this. Thanks.
