Every time I plug my watch to charge, it bugs me to download a map update, even though I updated (and even reinstalled) all maps using Garmin Express. If I let it download the update via Wi-Fi it gets stuck at 96%. I narrowed this down to either the base map or the Ski Active POI map, because it does the same even without the more advanced topo maps.
Searching the forums I found out that there are quite a few people experiencing similar issues. I tried everything suggested except resetting the watch to factory settings and start from scratch, which would be a major PIA. To no avail.
Also, the watch cannot calculate a route for turn-by-turn navigation, it's stuck forever at "Calcultaing route." This has also been reporfted and the conclusion is that it's a bug in Garmin software, I am surprised it hasn't been solved yet. I'm on latest 24.12 sw, but I've head these issues for quite some time.
