The new app for the Sena 20s to be able to setup your unit is very nice and makes live easy. But on the road it's not convenient to get your phone out of you jacked to make some adjustments to you setting, especially if you are wearing gloves! If you have a gps system (zumo 660, tomtom rider etc) that's already in front of you, and is made to be used with gloves, it makes more sens to have the app running on this device instead of your smartphone?
