I have BMW Apps on an iphone 4S working to send addresses to the car as well as sending from googlemaps.com. BMW Online works to see the weather etc. but the Internet option is a paid service, presumably part of Concierge.
I wish I could offer assistance on how to get it to work but my CA set it up before I arrived at the dealer for pickup and its worked fine ever since. I did hit the SOS button afer getting it home to complete the regiostration and add my emergency contacts etc.
I can certainly understand the frustration you guys and gals have. I have the same frustration with trying to play videos from my phone, not as crucial as having Assist but still one of the features I would use.
