Yes you need your m&m for your phone as your phone connects to that not your radio! As for display on the radio not sure never paid attention lol I think something shows on the m&m diaplay
Radio just says 'phone' when on a call but you set the call volume using the radio volume control. The M&M needs to be on but the radio can be switched off, the incoming call turns the audio amp on.
