they advertise that it works in Canada, but I couldn't get it to work. I had a US subscription, and it did not work in Canada. the system couldn't find a traffic channel for Toronto. When I called US support they said, call Canadian support as you want it to work in Canada. Called Canadian support, and they didn't know how to help.

NavTraffic is not a channel, its onscreen reporting of incidents, traffic flow, rerouting around closed roads, etc.
