If @Willie-Davidson indeed means TomTom Go.
Then the TomTom Mydrive Website is need to push the tracks to TomTom Go.
For TomTom Mydrive, a TomTom account is needed (Free account). Login with this account on the MyDrive website and in TomTom Go. In TomTom Go it is mostly one time. The app remembers it for future use. The same credentials are also needed for TomTom traffic services.
With the same credentials, you can also push a route from MRA Routeplanner to TomTom MyDrive.
Summarizing
Create an account on TomTom Mydrive and use it also in TomTom Go.
When it's done. It is now a 2 step journey every time.
