I did a preliminary investigation and it it seems that a single company sells
traffic data to all of the navigation system providers who then resell it as a
subscription service:

Garmin sells a special receiver called GTM 10 TMC Traffice Receiver (there are
newer models now). It sits between your car radio and the antenna, and
attaches to your Garmin device using a mini-USB cable. It would be
interesting to try and get this working with Neo900/OsmAnd (along with a paid
subscription).
