Noticed today that my phone icon on my steering wheel when pressed does not work.
It did used to work when pressed, so not sure if I have managed to switch it off some how?

It works fine... You can answer or reject call with them, finish call... To make phone call you must press phone button on satellite command for radio, then select "recent" or "phone book", select right contact (scroll wheel) and confirm it with OK button on satellite.
Or you can start phone call sliding and selecting on display, which is, for my opinion much less secure than first method...
