There is no button "ASL". It has individual knobs for balance/fade/bass/mid/high, so those are not accessed thru menu. I'm hoping there is a way to access a menu wherein the ASL is defeatable.
I need to toggle it because it reacts far too aggressively. Volume goes from very quiet to overly loud. Sometimes the logic is fooled and the sound will randomly change volume up & down...it will do this while sitting in traffic, for example.
This is what the radio looks like.
