I guess its a paid service.

What are the requirements to be able to use MyInfo via Google Maps™ (http://maps.google.com)?
If you are driving a 2008 X6 produced 4/08 or later or any 2009 and later BMW Assist-equipped BMW (except X3) and have a valid BMW Assist subscription, you will be able to send and receive the destination and phone number in your vehicle through MyInfo.
Pl correct me if I am wrong
