I emailed BMW for more info:
Thanks for your email about ordering Connected Package Plus.
I’ll be happy to provide some information about Real Time Traffic Information.
RTTI uniquely combines information from a number of sources, including other BMWs, GPS devices in smartphones and vehicle fleets as well as the emergency services to accurately present the current traffic situation to an accuracy of a few hundred metres.
Traffic flows are displayed on the vehicle navigation screen using a colour coding scheme with data updates every three minutes. Intelligent route guidance constantly looks for time efficient alternatives and recommends potential detours.
The roads on and around your route are clearly colour coded indicating the relative speeds being reported from our data sources. Green indicates free flowing traffic, Orange shows traffic slightly slowing, Red is heavy traffic and you can expect delays and Black is a road closed indicator.
If you’re unhappy with how this works for any reason, you can get a refund within 14 days from date of purchase.
I think I’ll go ahead and order it anyway!
