I was able to sync the phone to my G35 easily. However the car stores an address book which you can populate by sending contacts from the phone to the car via bluetooth. I don't see any way to do this on the phone. So if not, I have to manually enter the contacts in to the car's address book which is a real pain. Can the iPhone not send a contact via bluetooth? Page 39 of the iphone manual says "In some cases, your contacts list transfers to the car kit and you can start a call by looking up a contact on the car kit's display". But provides no other information on how this happens or how to manually do this.
