I got my 920 for Christmas and have been waiting until January 28th to use the promotional code to update the maps. When I finally am able to get in, I get a message saying that either my 30 days has passed or the latest map guarantee was not included by the merchant that I bought it from. I didn't think that it made any difference where you bought it from as long as it was new. What's the deal? Is there a DVD with all of the map updates that you can buy without having to spend $39 for each of the numerous area map updates?
