"I'm about to give up on finding a downloadable file for Washington state that works"

Essentially cgpsmapper was for creating maps and mapsettoolkit to put on your gpsunit. So they probably won't help at all.

You can head over to one of my maps, which is current at Washington is there along with Oregon, California and Nevada.  Several of the Washington maps here are individual and others part of the region, some are really old an/or dead links.  You can also head over to and maybe find what you are looking for.  At one time or another I've looked at most every map here and their.  I have some bias on my maps but you have some options.

Also, why not download the "Windows" version of the map you want, extract and copy the *.img to the Garmin folder on your SD card on your 30x
To Derek,
Not sure what directions you are referring to in the previous posts, but all my Mac version maps have a *.gmap. Once you have extracted the zip file you will have a *.gmapi folder (if Windows).  Depending on which extractor you used, you may need to open/left click one, maybe two times to open to reach the *.gmap folder.  If you see Product 1 you've gone too far and back up one.  Hope this helps.

I might be able to help  ;D .  I think something may be wrong with the installer as when I extracted it I didn't find a gmapsupp.img.  That could maybe be fixed with gmap tool, but I have it and can see this map in basecamp please follow...

Go back to the homepage and download the MAC version.  You will also need and advanced extractor like 7zip or pzip, both free.
-Find what you downloaded and it will end in .tgz, right click and extract to mntopo11.tar, again right click extract and you should end up with a folder mntopo11.gmapi, now left click once to open that folder and you should end up with mntopo11.gmap (no i).  If you made it this far we are ready for the next step, if not, start over.

Go to C:\ProgramData, you should have a folder named Garmin, (map need to show hidden folders) if not right click and create folder and name Garmin.  Open the Garmin folder and create a folder and name it Maps.  we now should have C:\ProgramData\Garmin\Maps, if so we are ready for the final step.  Copy the mntopo11.gmap that you extracted to previously into the Maps folder you should have your map now available in Basecamp and if you choose to "install" to your gps unit go for it.

This is my preferred way for the maps I offer as Mac versions can be used on both Windows and Macs.  It may look slightly complicated but it took less than 90 seconds from download to viewing the Minnesota map.

Let us know how it goes.

I've recently uploaded updated maps for Canada and Mexico.  I'm beginning to process US maps now so maybe later in the week they will start rolling out.  There won't be any significant changes to the maps, primarily updated data and minor/unnoticeable tweaks.  The one map I'm probably not updating at this time is Alaska.  For the last couple of years there is the "flooding" occurring in that area of the map.  When is is converted from osm to garmin things get out of wack.  As far as I know I'm the only map author who has kind of corrected this.  I finally figured out what was up and had to open about 20 raw data tiles in JOSM and make several edits/changes to the tags.  It was very laborious and I'm not up for doing it again right now.

Great, persistence paid off.  :)

As far as I know, only one mapset at a time.  You can do some overlays in several different formats, which it looks like what you have already done that were saved on your gps unit and then imported to basecamp.  As I was writing this I paused for a moment I opened base camp and then opened mapsource and did view two different maps.  So you might get a copy of mapsource

and see if that will work for you after resizing the windows.

"placed in c drive garmin maps"

This is where Basecamp and Mapsource will look for the .gmap


You may have to click "show hidden folders" in the view tab when you open the c drive to see program data and may have to manually create the folder structure

A short time ago I downloaded (my work computer) and unzipped, open to the gmap and copied over and as seen in the snip displaying in BC.  Does your folder look like this?

As far as updating I'm really not sure, if at all.  I got into this a few years ago for my own use then all of a sudden I had a bunch of disparate maps of the US and Canada, made some improvements and began uploading them here.  As my workflow improved, knowledge increased I began adding maps as time and interest has allowed.  Relatively few people anymore are making Garmin maps (see the Garmin/OSM wiki for others) some are limited area one and done and a few crank out the whole world weekly and I found my niche here.  It's a labor of love and I don't ask for anything and I don't really have a plan or roadmap and am just content if others find my maps useful for their purpose     

The SEA Topo is using fairly recent data FWIW.

I have maps available in both .img format and .gmapi format for the most versatility, some mapmakers only offer one or the other.  You should be able to unzip the "Windows" version and copy directly the .img file to the Garmin folder on the SD card in your Zumo AND/OR copy the .gmap to your C:\ProgramData\Garmin\Maps\ folder on your pc. You can view the map in basecamp and if you choose to, send the map to your Zumo

To view in Basecamp on Windows use the "Mac" version, after extracting and opening to mapaname.gmap, mapset can be placed in the Windows C:/ProgramData/Garmin/Maps folder (may need to un-hide and create)

Down load the mac version which ends in gmapi after extraction, inside is the .gmap which you copy that folder over...make sure basecamp is closed when you do this.  Your not really installing it, you are putting it in a place garmin basecamp can find it

Mmmm, not sure what is going on.  This site has usually not been the problem.  I'm going to upload to google drive and will pm the link to you later as an alternative possibility

Thanks for the interest in this map!

Earlier I downloaded both the "Windows" and "Mac" versions successfully with Firefox and a Chrome based browser.  We may need more information to see what's going on like:  Browser, OS, country, ISP, AV, folder permissions.  Are you getting any error message or does it just stop?  Let us know and we'll go from there.
Great news!  This should work for my maps or anyone else's for other readers that might have this or a similar issue.


I did a test and had the opposite happen, the map showed in basecamp, but not in mapsource???  I use C:/ProgramData/Garmin/Maps (you may have to unhide folder and create those sub folders) as my default location for gmap format of my maps and those of other mapmakers and I don't have issues.  Give that a go and see what happens.  My maps have been made and used/tested on a Win 10 machine and basecamp version is 4.71 fwiw
Thanks for reporting back!  That stuff at the end of the link is important, but I'm not web design smart enough to know why  :D

Do the same thing for this one , Eastern Canada/Maritimes if it's a problem.

Let us know what happens, thanks.

PS  IMHO, Having Firefox, even if it is the portable version and not your main browser is worth having around in this day and age for a variety of possible issues, this included.
