This is the one complaint I listed on my customer satisfaction survey. I came here to see if it was just something I am missing. Even the 6 year old after market stereo in my old car had folder +/- buttons. Not to mention, would play the next folder when all of the tracks in the current folder finished playing, where the Mini's system keeps repeating the current folder. It's dangerous to have to navigate the folders when you're driving. Seems like a simple software update that should be addressed.
