Voice Control

  mercedes/c-class/2008-2015

I have recently purchased a
2013 Mercedes-benz C Class 250 Amg Sport Blueefficiency Cdi, 2143CC Diesel, 4DR, Auto
When I press the voice control button on my steering wheel, the main console screen navigates to my navi screen and inform me that I don’t have a navigation system installed.
Is this a setting change that I need to administer to get the button to point to a voice control system or does voice control only work with a navigation system installed?
I wanted to use it for voice soaking in my phone.
