If you want to save space on your system disk, it is sufficient to copy a Shortcut to the GMAP folder instead of the folder itself.

Sometimes (for me, at least) Basecamp does not see the map in Program Data but does see it in C:\Program Files (x86)\Garmin\BaseCamp\Maps\

I have just uploaded a detailed map of France to GPSFileDepot. This is in GMAP format.

It is quite large - 6.5GB unzipped but includes every building, street names, woods, streams etc. It is mostly from IGN OpenData plus some itmes from OSM.

Corsica is in the map but not the French territories like Reunion.

cgpsmapper is (I believe) no longer supported. I use MKGMAP for compiling .mp files. It is much faster and free.

An important difference is that the tile limit (100/500) on KMZ files is per device (across all installed maps) whereas the 50000 limit for JNX is per map - and effectively no limit per device.

Yes, MAPC2MAPC (I'm the author) will make JNX files from most image formats. It will use GDAL (free) for the more complex ones like ECW. It is free to try.

There are shapefiles from USGS and USFS for landcover, transport, buildings, hydrography etc

For 'official' maps I know of Great Britain, France, Estonia and Finland - but not Mongolia.

GEOFABRIK has shapefiles made from Open Street Map.

All of these are free.

Thanks, Boyd.

The Inreach manual suggests the standard Garmin Topo maps are not compatible with the Inreach Explorer.

Is that true - and is there a way to make maps for it?

CGPSMapper is no longer developed. MKGMAP is still developed and reads .mp files as well as OSM stuff. For me it is much faster than cGPSMapper and I use it to create a .GMAP folder that can be copied  to Program Data/Garmin/Maps for Basecamp on Windows or processed with GarminMapManager on MacOS - instead of running an installer that updates the Registry.

I've had trouble with Chrome and downloads, too.

Sometimes helps to right-click the link and open in a new window.

Just an idea ....

Each map has a 'family number' and if you have two different maps with the same family number I think one can mask the other.
One of the JaVaWa tools (Device Manager?) might help to diagnose what you have..

Boyds maps are a good solution. But if you really need Garmin then this may have the trails you want.

It's in the newer GMAP format - copy the unzipped GMAP folder to c:\programdata\garmin\maps

You - or anyone else - might like to try this one (in the modern GMAP format).

Made from recent USGS and USFS data with some items from Open Street Map. Also the Bing buildings data.

The Oregon device may have a 'Map detail level' control that could make a difference to what is displayed.
