Hi I picked up my A class the other day and thought I had successfully sorted the phone out but when I press the voice command and for example say 'Phone Home' it asks me for the line number. Obviously I don't want to take my eyes off the road for me to find the line number, I just want it to dial home. HOw can I get it to do that. This is the first time I have had a car with hands free so would appreciate any help. I am reasonably computer literate for my age but this has foxed me and would appreciate any help.
