I am on a MAC and have Garmin Express, LT Map updater and Map Install. I am using Safari as an browser. I have a Garmin Zumo 660 and have Europe LM currently installed. So I have installed maps before. The issue I purchased North America LM yesterday and I cannot download the maps. Free worldwide Garmin maps from OpenStreetMap, available in Basecamp, MapSource, RoadTrip and gmapsupp formats for Windows, Mac OSX and Linux.

Garmin MapSource is not available for Mac but there are some alternatives that runs on macOS with similar functionality. The most popular Mac alternative is QMapShack, which is both free and Open Source.If that doesn't suit you, our users have ranked 9 alternatives to Garmin MapSource and six of them are available for Mac so hopefully you can find a suitable replacement.

Garmin Express is a tool developed by Garmin to manage your GPS devices from your Mac.
With this app, you can update urban and rural maps, register your device, update software and even backup your data.
Garmin Express also lets you install voices and vehicles for free, as well as download product manuals.
With just one click, you can update maps automatically, so you'll always have the most up-to-date routes. In addition, if you have many favorite routes and destinations saved on your device, the program lets you save them to your computer.
You'll also be receive special offers, update notifications, and you'll even have direct access to product support.

Garmin BaseCamp is a nice (and free!) software for viewing maps, managing geographic data, and planning routes. There are maps offered by Garmin and there are also free alternatives, usually based on the OpenStreetMap project. BaseCamp for Mac OS X uses a specific format—it’s usually a file ending with gmapi. Sometimes the free maps are not offered in this format, so you first have to convert them. As I always forget how this works, I created this page.

OpenMTB maps

Garmin App For Mac

OpenMTBMap is a project based on OpenStreetMap which offers detailed hiking and mountainbiking information. You can download a map for free here. In the following guide I have chosen the Alps map.

Requirements

You will need a Windows computer (sorry, but I don’t know any other way) with the following free tools installed:

Map installation

Copy the downloaded file mtbalps.exe to the Windows computer and start it.
Click on Next and select Mapsource-Qlandkarte_GT as layout. Choose a directory where you want the map to be installed, e.g., the default one C:Gaminopenmtbmapalps. You should now be able to see the map in Garmin BaseCamp.

Map conversion

Start Garmin MapConverter and select the just installed map. For the Alps map it is called FAMILY_6528. For other OpenMTB maps it will be called differently. You should be able to guess the family id by looking at the beginning of the file names in the installation directory of the map. Click Next and select an installation directory, e.g., the default one C:Garmin. After conversion is finished there should be a directory called FAMILY_6528.gmapi. This can be directly imported into Garmin BaseCamp on Mac OS X: simply copy this directory to you Mac computer, start Garmin MapManager and install it. Finished.

As a last step, I recommend uninstalling the map on your Windows computer. Go to the installation directory C:Gaminopenmtbmapalps and execute openmtbmap_alps_uninstall.

Garmin IMG format

Assume we have a map map.img in Garmin’s IMG format.

Requirements

You will need a Windows computer with the following free tools installed:

First step (GMapTool)

Copy the map map.img to your Windows computer. Start GMapTool.

Click on Add Files and select map.img.

Go to the tab Options, select MapTk, and select the directory where MapTk is installed.

Go to the tab Split. Select some empty directory where you want to save the parts of map.img created by GMapTool.¹ Select Compile preview map and enter some name describing your map. Select Set mapset FID and enter the FID and PID of your map. You should be able to get these numbers when you click on Info in the Files tab of GMapTool. Otherwise, try some random number between 100 and 9999 for FID.

Now, click on Split all. The process should hopefully finish without error messages. If so, you can close all windows and GMapTool.

Second step (Garmin MapConverter)

With the Windows explorer go to the directory you selected in GMapTool for the splitting process. Right click on install.bat and select Run as administrator. You should now be able to see your map in Garmin BaseCamp under Windows. Now, start Garmin MapConverter. Select your map (the one with the FID you have chosen above) and click Next. Choose some directory. After the conversion is done, there should be a directory called FAMILY_FID.gmapi inside the directory you have chosen (where FID is your FID). This file can be used for Garmin BaseCamp under Mac OS X: simply copy it to your Mac OS X computer and install it using Garmin MapManager.

I suggest uninstalling the maps under Windows. Go to the directory of the split process you selected in GMapTool. Right click on uninstall.bat and select Run as administrator.

In case you use Parallels, this directory should lie on the Windows drive since in the next step we have to execute a batch script with administrator rights and this does not work on a remote drive.
