OK so it worked. left the MAC as it should be and changed mine via macchanger. I did get to the license code in the about dialogue box so I entered the key that was there, it activated.....Navigation Europe. Bummer, I'm in the US and it was probably mentioned somewhere in the thread this would activate European nav and I didn't see it in the sea of posts, I wasn't the most diligent in reading the whole thread. Thanks for the help. Anyone who can help with US East? heh
