Navigation system does not work

Hello together I hope that there is no thread for this yet. We have our new Ateca FR 2.0 TSI since yesterday. Yesterday everything went without problems and today we get in and the navigation system doesn’t work anymore. It only says “navigation system is loaded….” and it doesn’t do anything. If one says a destination by language, he only indicates that the navigation system is not available. Software updates are not open… I’m pretty desperate. Does anyone know the problem? :/ Dear greetings Denise
