I think, GPS providers require users to use blue tooth to connect GPS navigator to a mobile phone in order to update via Internet or data channel of a smart phone.
I heard that traffic update was not accurate as it should.
Anyways what do you think about how to provide a solution?
--------
[1] Installing cameras everywhere in order to get snap shot of traffic as well as vehicle's travelling speeds? The traffic could be pushed to vehicles subscribed to live traffic updates via wireless Internet. This solution may get "privacy" issues with drivers.
[2] Satellite providers. I guess, all navigation devices are using the same satellite provider, i.e. military satellite networks.
* Hopefully on a road, there are many GPS users connected to GPS satellites at the same time. Thus, satellite providers [GPS controller] could tell if there are many cars driving under speed limit on the road. All navigation devices’ providers only subscribe to the controller in order to get updates. The info is then pushing to navigation's traffic subscribers using Internet.
- There is an exception; all reporting GPS navigation devices are in line to exist a road or highway.
* Your navigation devices could tell how fast you're driving and the speed limit on a road.
* I think, this is what they're doing.

[3] Why is the GPS provider using Internet to push out data about GPS users' speed or traffic issues?
- GPS provider or military satellite networks have collected data about GPS navigators and other stuff for themselves in a server or multiple servers on the ground.
- They only need to extract part of data to provide navigator's manufacturers, which used Internet to push out to smart phones connected to GPS navigators about traffic issues.
Updates: the only issue would be all GPS users lined up to exit a highway or roads. If GPS navigator providers could keep track of exit lanes, then this wouldn't be a issue. Anyway this is an odd case and rarely happened.
[4] Why don't they update satellite protocol to provide information directly to GPS navigation devices?
- You're dealing with military and government arms. They usually slow in processing a private sector's request. They're using satellites for their stuff.
- If they modified their satellite protocols, this would require a lot of backward compatibility tests. They have to ensure their existing stuff working.
