I just bought and installed the 2021 maps and MMI update. I think my original map was 2016. Don't know if it's any better yet as i have not had a chance to go anywhere. I do know that on my original map when i drove to Newcastle that on a few occasions my sat-nav thought i was driving through a field. This was because they have upgraded the A1M and needed to install some new sections of road. The next time i go there i should know if my update is any better.
