I think the problem with cell phone use while driving isn't the talking, it's the handling of the actual phone, dialing, hanging up, all the button type interaction. Once one is talking it's less of a problem.. although it can still be a problem because while you are talking with someone in the car, that person in the car is also aware of what's going on around the car and will have pauses in their conversation when things are going on that require attention, while a person on the cell phone will not.
Same with GPS systems while listening to the "turn right in 50m" instructions isn't so bad, poking at the keys to zoom or change destination and such while driving is far more distracting.
