The music plays fine when connected to USB or via Bluetooth but frequently the song displayed does not advance when the next song is displayed. If I hit a button such as the volume button on the steering wheel or radio the correct song name will then be displayed but the once the song finishes the next song won't be displayed unless I do it again. Sometimes it displays correctly but more frequently it doesn't. I don't think it's a problem with the cable because when connected to my iPod Nano it displays Hyundai on my Nano screen. Do you think there is something wrong with the Music player?
