Hello!
I recently purchased a bmw f26 2015 with NBT navigation, and I have the following problem: the sound level and quality is better when playing from the radio or the music from the internal hard drive, than from usb or bluetooth.
Audition is standard, not premium. Is there any coding in this regard? or another solution..?

2. How can I make the song list appear directly when the navigation opens? now the source/usb/media/ appears and I have to click 2-3 until I get to the song.. or when selecting a song after choosing it from "search folders" the list does not remain..

thank you
