Downloading phone contacts

Hi

Can anyone give me some advice on downloading my iphone contacts to my car.

I have just upgraded my 2004 C220CDI to a beautiful 2008 model with the Audio 20 system.

I can connect my phone using bluetooth and can make calls by manually entering the numbers, but I can't see how to upload my contacts from my Iphone.

The Audio 20 system has the ability to receive V Cards from phones, but I don't seem to be able to produce them from my phone.

If anyone can tell me how to get my contacts to my car, I would appreciate it

Thanks in anticipation
