Even with several years of updating various models of Garmin sat-navs, I have found the experience torturous at times.
You buy a micro/SD card preloaded with the Ireland/UK maps, you insert it into the side of your device and off you go.
After the first new upload syncs to Strava, your Garmin Connect activity history for the past 90 days will also sync within 24 hours.
We see occasional delays in receiving data from Garmin Connect, especially during peak upload times.
You connect your sat-nav to your PC or Mac using the USB cable that came in the box.
There is no solution at this time, and we recommend uploading files directly to Strava as explained below.In this case you update the maps on your sat-nav using Garmin Express which you download from Garmin's website and install on your PC or Mac.Once downloaded and installed, the update process is relatively straightforward.The Strava status page also displays uploads from Garmin Connect.One way to ensure a refreshed connection between Garmin Connect and Strava is to disconnect Garmin Sync from your Strava settings, then reconnect.
