MapInstall only passes partial mapping to GPS

General talk

I have downloaded the New Style map of Switzerland (CHE) in to BaseCamp on a Windows 10 HP Laptop.

In BaseCamp it all looks fine.

When I use MapInstall to transfer it on to my Garmin Montana 600, only a basic version of the map is installed (more like a base map).

Instead of the GPS receiving the 221 Mbyte map, I only get about 11 Mbytes with no detail and most searching giving no results.

I have tried this 6 times and also tried with the “old” Style mapping. Both give the same problem.

This problem has never occurred in the past. I wondered if Garmin are now blocking Third Party maps.

I am taking 15 members of a Walking Group to Switzerland next week, so any help would be most appreciated.

Roy, unfortunately the latest Garmin Mapinstall is corrupt, they are not blocking 3rd party maps but released a buggy update.
You’ll have to downgrade Basecamp to 4.6.2. See https://forum.openstreetmap.org/viewtopic.php?id=62468

Strangely, when I select a number of tiles which include the whole of Switzerland and parts of France, the whole of the map successfully installed into my GPS.

I used the maps extensively whilst our walking group was over there and they worked perfectly.
