iGO with the TMC/RDS

[victeamss]

Hello everyone, I wonder about a feature, I have Chinese car radio that does not have the TMC but the RDS, if I understood what I read on the internet, RDS and TMC are the same . Ie, retrieve data from radio waves, since the RDS transmits the data for the TMC ...

IGO should be able to use the RDS to operate the TMC, but none of my car stereos have access to TMC information

Is there a special configuration to be made in the sys.txt file or in the car radio?

Thank you for your help
