Unpairing cellphone to Bluetooth in GMC Acadia without Nav screen

[Paolino]

My friends have a 2011/2012 Acadia without a Nav screen (they have what I think is called the black tie radio or something like that).

 

They want to unpair a cell phone because apparently they have filled up the number of phones you can have paired.

 

Is there a command they can speak to do this or something they can access via the radio's menu?

 

They lost the owner's manual and online I seem to only find the newer ones with intellilink.
