The speed volume setting adjusts the volume according to vehicle speed. This function allows the volume to be set to a comfortable level while the motorcycle is stopped or traveling slowly. The volume automatically increases to compensate for engine, wind and other ambient noise factors as vehicle speed increases.
The speed volume setting also affects the voice activation (VOX) of the intercom. This prevents ambient noise from activating VOX transmissions when at greater speeds. It also prevents the need to continually adjust the VOX sensitivity setting.
Speed volume is also known as automatic volume control (AVC) on previous Harley-Davidson sound systems.

System Settings → Fade → Fade. Select
Fade/Speed Volume.
Adjust speed volume to one of four different levels. Each level defines the amount of gain that is added to the volume as vehicle speed increases.
NOTE
Setting speed volume to the lowest level effectively turns off this feature. The volume remains constant while riding. However, the radio has equalizers with dynamic filters which modify certain frequency bands depending on speed. So there may still be a change in sound as the speed changes, even with speed volume turned off.
The effects of the speed volume will be less noticeable under certain conditions, such as when the volume is already turned up near its maximum setting.
