F.A.Q.
Our maps work on all Garmin devices which support uploading maps.
What should I do with a gmapsupp.img that I downloaded?
It sounds like you are trying to double-click, or otherwise open, an .img file intended for a Garmin GPS.
Installing the map onto your GPS
- Connect your Garmin to your computer via a USB cable.
- Put your Garmin in USB Mass Storage mode. (On an eTrex, this is typically done by going to the menu screen, then Setup → Interface → USB Mass Storage.)
- The Garmin should show up as a removable disc (like a USB stick) in the usual place. On a Mac, for example, this will be on the desktop.
- If there isn’t a folder on the Garmin called ‘Garmin’, create one.
- Into this folder, copy the .img file that you downloaded.
- Rename it to gmapsupp.img if it’s not already called that.
- Eject the Garmin as you would a USB stick. Again, on a Mac, you do this by dragging it to the trash.
On Windows – No memory card
- The easiest way is to use Garmin sendmap, a command line tool, which sends the gmapsupp.img file to the Garmin device. Already existing maps will be overwritten, so create a backup first.
- It is also possible (didn’t work for me with a Vista C) to transfer any section of a map together with all maps on your unit after the map has been registered in MapSource. There is a section on how to do that (This is the same as the method above): OSM Map On MapSource. After integration of maps, in MapSource select ALL maps at once. That works across different map sets as well. Then choose “send to device”. The transfer will take quite a while.
Can I use these maps on multiple Garmin devices?
Each map license is valid for one device only. If you want to use the maps on additional devices, you need to purchase separate licenses.
Do I need an internet connection while using the maps?
No, once the map is installed on your Garmin device, it works completely offline without requiring mobile data or Wi-Fi.
What should I do if my download link doesn’t work?
