Hey...saw no one replied to this. So...what phone do you have? This makes all the difference. If it's an iPhone (like me), there is only the calendar via the BMW Connected App that is available. Email and your calendar via Office in iDrive doesn't come through. (apple issue). The BMW Remote is for unlocking, precondition, and location info (within a certain radius).
So...the BMW Connect - that will get you the EcoPro Analysis data if you care. It will also give you Facebook, Twitter, and news (RSS) feeds on the screen. For the other apps like Pandora, you must run those outside of Connected on their own. Anything you play in Pandora will automagically pop up on the car's screen.
BMW Apps require a mobile phone.
As for Assist/Concierge/Online - haven't been able to do much since my account is having issues because of the 2014 model.
