As reported on the Garmin Express PC sub-forum, the long awaited Honda map update 2019.0, which appeared on Fri 21 Dec, has been withdrawn. All attempts to download the update on both Mac and PC failed during the local processing phase. It affects Honda CRV AND Civic among others. Very annoying.
The map update for the Honda head units has not been pulled. If you are not offered an update in Garmin Express, please contact Product Support in your region to troubleshoot the issue.
