after today maps update 2019.20 the reboot and map loading takes very long time?

I ended up reinstalling the maps. My battery went from 100% to dead overnight and watch was being weird, but after reinstall of map update works like a charm again

I just updated my maps EU topo. Restarted the watch and no problems

After reinstall the loading maps for the big map took about 4 minutes to halfway and about 13 minutes to complete.

After hard reset (15s power button) it loads the small maps also slower that I reinstalled.. and the big map is taking about the same, so the situation just got worse by reinstalling.

I think next I'll try to delete the map data from the watch manually and then reinstalling.

But won't recommend reinstallation as a fix, but YMMV.

Reinstalled the map with Windows, with latest Garmin Express, so don't much know what to do there either.

I cant even update the maps onto the device, Step 1 of 2: Preparing Device for Map Update takes forever not a minute as they write...

I didnt get new FW update, but got new maps. They are loading after  disconnect from PC for about 10 minutes and got about 90%... if i would need restart before race, i would be angry.

Garmin, why you are adding more bugs than features to your products?

The same problem on the MARQ Expedition ... expecting an answer from Garmin  ... !!

So moved all these from the watch away, now it's fast again! :D But of course, no maps.
BTW. That gmapsup4.img is openstreetmap I installed.

And now reinstalling the maps..

After installing it was normal fast. but hard reset, is about one or two minutes. Normal power off and on it's under 30s.

So probably managed to fix it :) gmaptz.img was generated when connecting back to Garmin Express. Its probably the timezone data.

And now comparing what files are missing:
0926217189.gma
D6185060B.gma

And my openstreetmap gmapsup4.img. No idea what are those two .gma's.

And for the fun, md5 sums from the old files:

edda604b83dd1ffbe68828ffc2e90bba  gmaptz.img

And compared to new ones.. The .img files are identical, but gma files have changed:

D6185070A.gma: FAILED
gmapdem.gma: FAILED
gmapprom.gma: FAILED
gmapsup1.gma: FAILED
gmapsup2.gma: FAILED
gmapsup3.gma: FAILED

So what can we learn about this? I don't know :D The maps where good, but those .gma's had something that caused it to be slow.

What else do you have on there? Any CIQ watch faces, data fields etc. Just updated mine and it fired up as normal after a reboot - press and hold top left until shuts down.
