Thanks for help guys, but this really is not good, I have a Tom Tom sat nav with traffic, it works out the box, Hyundai sat nav that advertise's traffic should do the same, IMO!
I found out it's Classic FM, I think I link up my phone. Not that I wouldn't mind a bit of Classic FM but not all the time, something you have to be in the mood for and that ain't to often with me.
I didn't think that the built-in SatNav used the radio traffic data, as my old Megane with TomTom did.
If I need it I just enable WiFi hotspot on my mobile so that the SatNav can use it to access data across the mobile circuit. As far as I can tell the usage is very low, but I don't use it every day.
The better designed infotainment systems do use the data transmitted via FM radio, but the problem with the Hyundai system is you have listen to the station transmitting the data. The Ford Sync II system has multi FM tuners so you don't have to. I miss the Sync II, as in my opinion, it was far superior to the Hyundai offering.
