Thanks Boyd!
Got it to work. But had to find a windows machine. Unfortunately, the author of IMGFromGPX hasnít updated the Mac version to work with the new security requirements of a modern OS-X Mac operating system.
OK, but after getting my hands on a windows laptop, your instructions were dead on.
Thank you very very much !

These two simple programs can convert a .gpx file into a Garmin .img file overlay, maybe they can do what you want? The first one is free:


If you want to do something fancier, there's Mapwel, but it isn't free


Or you could use cgpsmapper and a variety of other free tools, but that is more complicated. Sorry, I don't use the OSM tools.

I am able to convert the KML file to GPX using GPS Babel, then pull it into a layer in JOSM Editor. But I am lost after that.

I'd like to display the maidenhead grid boundaries (4 digit) on top of the USA. right now, I was able to take a KML file and get a whole bunch of tracks that I can turn on or off, but I would much rather have a map that is on all the time (so I can actually see the grid squares' boundaries with other maps under them.

Anyone know of any such map, or can point me in the right direction on how to make one? I am on a Mac, so some of the tools will not work for me.

thank you

Try using MapInstall to create a .img file on a USB drive then copy it to the Garmin directory of your Fenix.
Thanks, sadly Javawa's software can't run on a modern Mac with the latest software.

I am really excited to find this site and be a member, this being the second time logging on after beating my head against the wall as first time GPS owner (66s). Having figured out a few things, just downloaded my first set of topo maps (New Mexico) via this site (ever grateful), the 66s geocache stuff may be horribly out of date,  manuals and videos are not enough, having no coach is painful (from beating head on wall).

Having said all that, it would be awesome if there are any Albuquerque residents that would be interested in being annoyed with my presence as I learn the craft. I would like to learn geocache, I own an adventure bike (BMW G650 X Country), want to backpack eventually (swimming to lose weight and get fit at the moment). I retire in October next year and plan to spend much time wandering about. I drink beer and coffee so if there are any groups who get together here in town. I can meet anywhere. I'm also a member of the Albuquerque Press Club and can host GPS related group activities there, no food but there is a bar and you can bring all the food you want. Any takers?
Haha... Garmin is still living in the 1990's in some respects. With 2020 just around the corner, they really need to get beyond FAT32. Their own City Navigator EU map will no longer fit into a 4gb file and has to be broken into two pieces. And there are a number of things about their map format itself that really should be modernized. But as long as they can keep it working, there's not much incentive to make big changes - especially when they would lose compatibility with their old devices.

Anyway... you should be aware that there's another serious limitation that can bite you when installing multipe maps. Your device has a map segment limit - segments are the smaller tiles that make up the whole map.


If you install more than 3000 segments, you will have problems with some of the maps. The results are not consistent, and depend on the exact maps you install. There are no standard sizes for segments, they could cover a whole state or just one county. But, typically speaking, you will hit the map segment limit by the time you fill up a 4gb SD card. So "bigger is better" is not really true when choosing SD cards for a Garmin GPS. An 8gb or 16gb card will give you more space than you can actually use for garmin maps.

There are several ways to check your segment count IIRC. Javawa's free device manager program should do it, and is also handy for other things

Ah, I missed the whole "it has to be FAT32" formatted. I believe the max size for FAT32 partition is 32Gb, so looks like I have to buy some smaller microSD.

thank you for the help. I loaded them on an old 2Gb micro SD card and they worked.

I feel like I went back 5 years in time... Glad I save the old 5 1/4" floppy disks... you never know when you will need them.
