My CA confirmed it does not appear to work on any BMW model they have delivered. So it might not be available in the USA. He had told me when I asked that BMW does not support remote start. Maybe they are nervous about providing this functionality for legal reasons in the US. Remote venting is letting the car run fans unattended.
He is now working more to solve my ConnectedDrive-not-working problem. Hopefully he finds someone who knows what's going on. So far I have been unsuccessful.
