Hi. I've asked this question in another post with no replies for some reason. Thought I'd try again. Usually when I listen to music, spotify, over bluetooth I can't see any music info. I can't see the artist name, song title or album name on the dashboard screen. But once and a while there appears a (-1) symbol in the top right corner of the screen and I can see all the music info. My question is how do I get the music info to always show on the screen and what is that (-1) symbol? Has anyone had this issue? I have a 2011 535. Thank you for any help.
