First, i would like to apologize if this thread already exist somewhere in the forum. Search did not return with any satisfactory result. I have a 2006 GS. Is it possible to upgrade the navigation to the one currently in the 2007 (better graphic, etc)? If it is, how much would it cost me? Secondly, how do I update my maps with newer roads and more up to date POI list? Thanx in advance
