Guys,
i know how to go to the next folder through the navi screen. My question is how to do it on the 2015+ model without having to turn the screen on and go through a bunch of steps. Just want to make sure I didn't miss on any button on the stereo or the steering wheel to do this.
Doesnt matter if you organize your folder by artist, genre, whatever.

 

Nope, it appears that there is no way to do it other than the main screen. Seems silly, but the updated manual (for 2015) describes each buttons' use and there's no reference to advancing the folder (like in the older models). If you hold the button down you'll just get fast forwarding through the song.
