There is about a 200 page book that comes with MBs that have COMAND. In other words, they are quite complicated.
I don't know about the ML series, but on mine there is a TEL button that you press to get to the phone screen. After that there is a telephone keypad on the COMAND unit from which you can dial a call.
The Bluetooth adapter, aka the puck, updates an obsolete MB phone system to one you can use now. The adapter fits into the older phone cradle that formerly recharged the phone and interfaced with it. It essentially adapts the old phone system to the Bluetooth technology and compatible phone.
If you want more detail, I suggest that you perform a search on the Benzworld Audio & Telematics forum. Trust me, you can read about these issues for hours.
