Modus factory phone controls

Evening all,

I hope this is in the correct place?? Tried searching but nothing found on it,

We have recently been gifted a modus by the inlaws, nice little car, wife (her parents) loves it,

On the steering columb there is a set of phone buttons, answer, end call and a middle one, had a look in the manual but didnt see anything obvious, Simple queston really, does this mean it has a phone kit fitted?? If so, how does it work please??

Not found any obvious buttons butnot look too indepth as its 'her car' ;-)



Thanks muchly in advance.
