i have a 2005 STS and i copied the navigation disc from the corvette and saab 9-5 for the european data.
the navigation works fine the only problem is i canīt input a address or a poi.
i can save a point and let the navigation navigate to this point.
but i canīt put into a address oder change the country it doesnīt display the map with the countries... sometimes it does it but i canīt change the country..

what can be the problem? i uses different + - dvdīs and burned it with different programms at the lowest speed..
maybe itīs a problem to copy a copy and not from the originally disc?

any ideas?
