mercedes sat nav update

Hi, I've just bought a second hand Mercedes benz B class diesel B180 CDi sport 2010 (I'm so excited) and collect tomorrow.

The car has the sat nav discs with it but they are the 2010 ones and need to be updated.

My daughters friend has a 2017 Merc A class with discs, can I borrow his discs to update mine or doesn't it work like that?
