Who knows? I ordered a Aufi Q3 Sportback with navigation preparation (series), phonebox, smartphone interface and VC Plus. I wanted to save the Navi for over 2000€. My question: if I want to unlock it afterwards, what has to be retrofitted or is enough to activate it. And what does that cost about? And can you book the Navi e.g. also only for 1 month? Thank you.
