According to BMW the online function is not supported by the current TCU that is available in the USA. Personally I'm all for interent use in the car. Given the traffic situation in the states and the fact that you can barely break 15 mph in major cities it will be something to do while you are getting later and later for your appointment...

Of note though, looks like europe already has high beam assistant, so that will surely be coming down the pipeline to the USA. I still don't understand why the X5 doesn't have night vision though (USA or Europe) since it seems the most obvious choice for this car.
