ANDROID TMC Data Traffic

Could someone explain how TMC works

Does the data source need to be online ( I assume uses phones data connection to receive information ) or can it work offline?

I have no events and the traffic events is greyed out. The attached image shows green text stating 'Online Traffic'







info in sys txt is

[http]
enabled=1
can_use_native_api=0

[tmc-http]
enabled=1
profile_name="nng-igo-tmc-jci"
;profile_name="nng-igo-tmc-russia"
;profile_name="nng-igo-tmc-beckerfull"
;profile_name="nng-igo-tmc-iphone"
profile_version=2
udp.enabled=0

[tmc.src.http]
enabled="1"

Finally, license are ok or at least look ok.




Thanks

Lee
