SF2 - Audio Overlay

Enabling/Disabling Audio Overlay (Default: Disable)

Audio Overlay allows you to hear the audio from two features simultaneously. When Audio Overlay is enabled, phone calls, GPS instructions and intercom conversations can be overlaid with audio from the FM radio, music or GPS app instructions from a smartphone in the background with reduced volume. Increasing or decreasing the volume of the audio in the foreground will also increase or decrease the volume of the overlaid audio in the background. The volume of the foreground audio can be adjusted using the headset. How much background audio that is heard can be adjusted using the SF Utility App or the Sena Device Manager. HD Intercom and Audio Source Priority become disabled temporarily when Audio Overlay is enabled.

** Only one background source can be heard at a time while listening to an audio source in the foreground.

A. GPS instructions can be heard during phone calls and the volume level of both audio sources can be adjusted using the headset.
