Anyone know how to "Restore Factory Settings" or "Restore Defaults" or basically erase all personal information such as navigation destinations, contacts, telephone numbers, music store on the built-in hard driver, profiles, etc from the new F01/F02 7 series? I'm trying to sell my car and would like to erase all personal information from it before giving it away.
