Upgraded in Jan 2020. This update was worse than the previous version for my area. Speed limits were over the posted limits and the previous version was more accurate. Hope the new version corrects those errors.
Also have the January 2020 map version but my 3 year subscription expired in May. Not sure it's worth upgrading to every new map - especially since I upgraded to the Android Auto feature but it requires a smart phone connected via USB cable.
