It would be a great feature to allow the bluetooth-connected phone to record audio being broadcast through the 20S unit. I see three use cases:

1. Record conversations through the RideConnected app.
2. Record rider's microphone through direct connection to phone.
3. Record full intercom conversations (all parties).

Since the RideConnected application is already accessing the bluetooth audio stream, adding a record button for case 1 seems trivial.
