An interesting point covered in the videos is that the internet service is routed through BMW proxies - meaning both that no anti-virus or other protective measures are needed, and that all traffic on your annual subscription will be going through a BMW computer before being relayed to your car. BMW insists that surfing is not limited nor restricted in any way, however. Unlike Chrysler's system, BMW's ConnectedDrive does not require a separate mobile phone subscription.
