@ jolly47roger - I have enjoyed our discussions and am very impressed by your maps and software. But that response is misleading and not very helpful. I don't use BobT's maps, but they are popular, he has a presence in the forums here and has been happy to help users with issues.

@ jonemiles - I think BobT's maps work on Backcountry Navigator, these are not Garmin format maps. A quick search of the site for "BobT" will probably answer any questions, or contact him directly if you're still having problems. See this for starters:


or this:


.kmz files are actually "containers" that can hold many different types of data. So your file could be almost anything and you haven't given us enough information for a proper answer.

But a common use for .kmz files is Garmin "custom maps" which are scanned images of paper maps or aerial imagery. If that is what you're trying to use, forget it. That kind of map just isn't compatible with an old device like the 60csx.

Now a .kmz file might also contain waypoints or tracks, and those should work on the 60csx.

General Discussion / Re: View a topo map in another state?

How did you install the map on the GPS? If you used the current version of Basecamp/MapInstall, that is likely to be the the problem. The Windows version of this software doesn't work properly with most maps on this site. See this thread: https://forums.gpsfiledepot.com/index.php?topic=4539.0

A variety of other things might also cause it, but this is the most likely cause and it's been a problem for just about everyone who uses the maps from GPSFileDepot.

Map Making Support / Re: Having Issues with Compiling

FWIW, it typically takes me from 30 to 60 seconds to compile .img files in the 2MB - 3MB size range. Sometimes they might take a little longer, but I make very complex maps. I am using a dual core core i5 3.4ghz 8gb PC running Windows 7.

Had just a quick look at Oz's tutorial, and it seems that he uses tiles based on USGS 100k topo maps. My own maps tiles are generally based on USGS 7.5 minute quad boundaries, but my maps mostly cover smaller areas and have high detail.

That is true, but it still works just fine and I don't think the fact that it's been discontinued is relevant to the OP's problem. This sounds like something specific to the tutorials that Oz has created, and I've never used those myself so I can't help.

FWIW, I just received a PM a few days ago from somebody who was having cgpsmapper issues. He contacted Stan (the cgpsmapper author) and actually received a helpful response. So, even though the software is no longer under development there's evidently still some level of "support". :)

Glad you finally got it working. FWIW, there was no reason to uninstall Mapsource. That program was discontinued long ago and it still works fine.

Garmin is transitioning to "Garmin Explore" which is web-based software for managing its devices and your GPSMap 66 is one of the new models that support this new system.

Was just reading a review of the new Garmin Overlander that uses the new "Explore" site.... if you use this, make sure you have good local backups of your important data!  ;)


"While track and waypoint syncing is supposed to be a highlight of this system it did not work for us. After multiple attempts and even creating a new account in an attempt to get our data to sync… it lost our tracks from the past 2 months… all of them. "

I think the options are very different in the EU. Check Garmin's site in your country to find out what map is included. It may be a "topoactive" map (or something like that) which is pretty new and I don't know if they are routable. The 24k topo maps are US products (named after USGS 24k maps, although they are actually completely different) so you won't have those available. In the EU, OpenStreetMap is popular. Not so impressed with it here in the US personally. But their maps are free and they are routable. See this:


You'll have to check your device specs to see how many points can be included in a route. This gets confusing, with different specs for different models. But you may run out of points if you're creating complicated routes.

Garmin handhelds also have something called "track navigation" where a track can be treated like a route. This would let you create something more complex, although I've never used that feature myself. Tracks can typically have 10,000 points, routes are probably something like 100 points.

Enjoy the new GPS!

Your GPS will have Garmin's 100k topo pre-loaded. This map is not routable, and is not very highly regarded by most people. That being said, it certainly has its uses. The advantage is that you get coverage for the entire US and it's always available without installing anything else.

Yes, "routable" means that the map supports turn by turn navigation. Maps have to be made in a special way to support this. The 100k topo, and almost all maps on this site, are not routable. That means it will show your position on the screen but there's not data about the roads that can be used to generate a route with turn by turn directions.

Garmin's 24k topo maps are completely different, they contain the same routable roads as City Navigator. But each map only covers a few states and it's expensive.

On a simpler level, you can create routes on any map that will send you in a straight line between points that you choose. Garmin calls this "direct routing". When I mentioned "user data", I'm talking about points that you create (waypoints), tracks that you record (showing where you've been) and routes that you create. This data is completely separate from the map and can actually be used without any map at all.

I don't think qGIS will do much for you. It is GIS software that is better suited for more advanced uses, such as working with shapefiles and raster imagery. It certainly could have its place in a map-making workflow, but since you describe yourself as a "complete newbie", iMO... it's not for you. Garmin devices are consumer products that are intended to be used with consumer-level software. qGiIS is certainly not the right software for creating and managing routes. And qGIS cannot manage Garmin maps.

On the Mac, I think Basecamp is pretty much your only option. In order to use routes, you will need a map installed on the GPS that supports routing. Almost none of the maps on this site are capable of that. Garmin City Navigator is the standard map for routing, but Garmin's 24k topo maps are also routable. Both of these options are rather expensive. To create routes, you will need the same map installed on both your computer and GPS for the best results.

Looking at your post again... it looks like you aren't quite clear on the difference between "maps" and "routes". I think you are really just interested in routes, POI's and tracks. These are considered "user data" and maps are like "system data". Basecamp is a program for managing your user data.

Basecamp does seem to be at the end of its life (although Garmin has sent some confusing signals). The current Windows version has an issue that makes it incompatible with many (if not most) of the maps on this site because it doesn't work with registry-based maps. This is not an issue with the Mac version of Basecamp, because registry-based maps were never compatible with the Mac. :)

Garmin is transitioning to "Garmin Explore" which is web-based software for managing its devices and your GPSMap 66 is one of the new models that support this new system. I have no experience with this, and don't have a compatible device. But that is clearly their future, so you should probably check it out. In the future, it may be all you need.

GPSr Units / Re: cannot load OSM onto Drivesmart 61

Garmin stated that they discontinued basecamp in a FAQ on their site. Just went back and now they have removed that statement. However, the reality has not changed. The last update to Basecamp was May 2018, and they obviously have no interest in fixing the incompatibiliy with registry-based maps.

If you are using Basecamp 4.7 (released in May 2018) then that is likely the problem. This version of MapInstall does not work with registry format maps, which is probably what you have. This has been a huge problem for everyone, but Garmin has discontinued Basecamp and will never fix it.

See this thread for some solutions, which include downgrading to an older version of Basecamp or using Mapsource, Garmin's old software.


If you want to use Mapsource, there will be another issue on the DriveSmart however. Automotive devices are recognized as MTP devices and not USB disks on Windows computers. This means Mapsource will not "see" your GPS. But you can change this with a hidden menu on the Drivesmart - see this


2. Start NUVI by itself and go to Volume Screen.
3. Press the upper right hand corner of screen for 10 seconds.
4. The Developers Screen will pop up
5. Scroll down to MTP SETTINGS

It would help if you were more specific about the map. Is this it?


That map is hosted on another site here:


You will find installation instructions on that page. You should not be messing with .img files directly, that map has an installer to handle everything for you. It's not as simple as just copying the file with this type of map. Putting an .img file in the Garmin folder on your PC won't work.

This map is more than 10 years old and uses Garmin's old "registry format", like many of the maps at GPSFileDepot. A year ago, Garmin stopped supporting this type of map in Basecamp (athough they never explained this change). The result is that you can view the map in Basecamp, but it will not install properly on a GPS. Garmin has now discontinued Basecamp, so "it is what it is".

With an old map like this, use Garmin's old Mapsource software. That's what this map was intended for. Run the installer and the map should appear in the maps menu in Mapsource. You can then send it to your GPS. For help with Mapsource, see these tutorials:


As you have noticed, Mapsource works correctly but Basecamp is broken. And Garmin has discontinued Basecamp, so it will never be fixed. But there's a pretty easy solution that doesn't involve installing anything.

Mapsource always names the map gmapsupp.img, because that's the only filename that very old GPS unit recognize. Your etrex will recognize any file with an .img extension however. So, choose one map and send it to the GPS with Mapsource. Now manually change the map file name from gmapsupp.img to map1.img (or anything else you like).

Then send the second map and change the name to map2.img. Repeat this for every map and you will be all set.

Using The Maps/Garmin Software / Download problems at boydsmaps.com

Last weekend a user informed me of problems downloading one of my maps. To make a long story short... I finally traced the issue to a plug-in that wasn't compatible with the new Wordpress software on my website. To make things worse, when I attempted to update the plug-in, the process failed, corrupting all my download pages and making them blank!  >:(

Sorry if you've been unable to download any of my maps, not exactly sure when this problem started but I suspect it's pretty recent. Am going through my whole site now and fixing the problems, but it may take another day or so to complete. See this support thread for more detailed information:
