Transfering contacts to in car phone book via bluetooth

Hi I have recently bought the new nissan pulsar and its intergrated voice dialling only works through the cars phonebook.

Problem is I cant find how to transfer contacts from my iPhone 4S to the car. I have the menu open and ready on the car but can not find the option on my phone to transfer via blue tooth. This is a pretty standard feature on most cars these days so you would think you could do it with an iPhone.

Any suggestions/help?
