My wife and I are moving to Germany in a couple months and would like to know if the stock navigation system in our 2007 GMC Acadia will work in Europe. I have tried to find a European disk online, but haven't had any luck. I have also called GM and the GM Navdisk people and they couldn't help either. Has anyone brought a North American Acadia overseas, been able to purchased a European Map Nav DVD (if they make them) and had the GPS work? Help.
