there is no way to transfer your phone phonebook to the Civ, other than by manually reading them out one by one
which isn't great
And yes, if you dial from your phone then
some phones auto transfer the call to the
HFT (think my D900 does), but most don't.
'redial' is indeed the way to go and Tom says, or similar to mrh, you can press the steering wheel
HFT button and say 'transfer'
Although obviously you don't want to be fiddling with your phone whilst driving...
