The tomtom live has a pay system that works pretty well at big cities at least. From usage patterns they know about congestions and change the route on the fly to avoid them.
From "usage patterns"? My car's built-in GPS gets the info from the FM radio, as does my Garmin.
TomTom Live use aggregation of usage patterns of their users, uploaded via the internet connection those models have. They don't have an FM radio, nor connect to the car radio. This is documented, because you have to give permission.
TomTom is very slow at correcting errors in their maps. They claim that they just buy the maps from another company and that it is their responsibility.
There are specialist companies out there that do nothing but collect map information and prepare it for their subscribers - Garmin, TomTom, the car manufacturers, Google etc.
Yes, I know. Once I wrote an email to TomTom comparing the map shown by the device, by google, and by the local authorities. Only the map made by the local authorities was correct, at least about the roundabout I was reporting. They acknowledged the error, but said it was up to the map provider to correct the error, which was quite important. I had to drive that way very often, and it was a nuisance hearing the wrong instructions. Not because I would take the wrong turn, but because I had to ignore the very talkative lady at the dashboard giving the wrong instructions :-) From initial report it took them about 2 years to get an updated and correct map. It is possible that they are faster at bigger cities. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
