Change your radio mode from Oceania to Europe. Then TMC will appear.

To do this go into radio service mode and scroll through the options until you see OCE or OCEANIA. Change to Europe.

However, you also need the TMC database on the map disc - do you have that? I doubt it.... Without the TMC database, the nav doesn't know the lat/long of each TMC location ID. The TMC database has to be issued by BMW (well - by the mapmaker...)
