We live in Iowa and bought a Tomtom One about 5 years ago and have never updated it. We don't travel much but it has been very helpful when we did need it. But I tried to put in an address in Rochester, MN and it wouldn't recognize it, this is a house that has been there for over 10 years. I went to the Tomtom site and got a free update, tried to put in the address and it still didn't recognize it. So I'm thinking I need new maps?? What will it cost and is it worth it? I see that these devices have come down drastically since we bought ours. Any help would be greatly appreciated. Julie
