I'm looking for help setting the volume of different sources for the 10c pro.

By "sources", I mean:

1. The volume of the sena voice prompts (like "phone connected") and general beeps
2. The volume of intercom pairing with another 10c pro
3. The volume from a connected phone - in particular, google maps.

In order to be able to hear a paired intercom, I rotate the jog dial after connecting to the other 10c pro. But this also makes the sena voice prompts and beeps exceptionally loud. Painfully loud.

The sena website indicates that different sources can have their volume set independently. HOW? Is this affected by the "audio multitasking" setting? Should audio multitasking be on or off if I want to be able to have an intercom conversation that is occasionally interrupted by google maps giving me directions?

What does the "background volume" setting change - intercom, or google maps, or the sena device? Which one is "background"? Does audio multitasking change what the "background volume" setting does?

Documentation on all of this is very, very unclear.
