Yes, they simply supply the data to Garmin. Have you seen this thread though https://forums.garmin.com/apps-software/mac-windows-software/f/garmin-express-windows/207081/cyclops-europe-database-updates---no-longer-available-via-garmin-express---now-resolved
Still no updates!!!! If Cyclops are responsible one would have thought that Garmin would have sufficient clout to sort it. Will I be getting a rebate for the months of no updates? Is there any point to me renewing my contract? This happens every year so sort it Garmin.
Are you sure you're looking in the right place? Did you look at the link I posted above?
Updates are not announced anymore, if you follow the directions indicated in Sussamb's link thro' Tools etc you have to download the entire database each time to be totally up to date.
