I have a N1 that I updated with ebay 80MT East disc. After the update everything worked fine I could use all the navigation functions - no problems.

Also sometimes it will say to insert the appropriate disc. And it will not let me use any of the address searches or anything. I did the bypass exactly like it was said in the other thread so I don't think the problem is there. I have know idea what it
