I have a 15 ultra limited. 6.5 boom. have had the screen lock on lets say a nav window and no matter what I tried, shutting off bike pressing all buttons it stayed on that screen.. I said f it for the evening and left it. next morning was working fine. I have also had it off and then started it is on. or it was on fm turn bike off then on and screen was on cb... my o6 harmon did the same thing so that part doesn't upset me... the avc... I assume auto volume? if that is what people are referring to I don't know If mine works.. I have it set to high and compared to a car I really don't hear it increase so.....??? can you guys really hear a big difference? as far as speakers and sound.... It is far better then my 06 ultra. I can hear my radio at 70 and actually understand what is on. and from what I researched I think I will go for the j&m setup if I want improvement.

So guys please respond to the volume control... That is the only thing I have a concern over.
