A class audio unit

[Philc57]

I've been looking at the A class online as a possible replacement in the future
Can any one answer this question. On the radio unit I noticed numbered buttons, are these buttons presets for other functions like making phone calls and for favorate radio stations
I do miss that on my present car

Let say 18 plate, a200, no idea on the unit, but any one who has one will be able to say what these buttons do

Should change the radio pre-sets when on radio & when in tel mode you can use the buttons to dial out as on your phone, steering wheel buttons will bring up your recent calls & you can call back from those buttons.
