Starting with the 2014 model year, BMW has integrated a more advanced system to give you information on any traffic in your area. Called the Advanced RTTI (Real Time Traffic Information), it uses a faster connection and multiple sources to give you the latest information to help you avoid traffic.
It uses a cell connection built into the car that updates the information every 3 minutes! Advanced RTTI also gets information from other sources such as:
-traffic sensors in the road;
-GPS data from fleet vehicles;
-cameras on bridges
It is a very comprehensive system that is very beneficial to the BMW driver! To watch this in action, look at the video below:
