How to use/install the maps

Download your country file(s)

Choose a country from the table of the startpage and download the *.img file to your computer.

Copy to your GPS

Connect your GPS with your computer. With current systems that works with an USB cable. Move the *.img file(s) to the SD-Card of your device, into the "Garmin" subfolder, for example E:\Garmin\country_gmapsupp.img If the folder does not exist, simply create it.

Save the files to this example location

An example location of your SD-Card with multiple maps

On modern systems you can have multiple .img files in this directory and activate/use the maps simultaneously. But note that you need to rename the file to gmapsupp.img on older devices, e. g. eTrex 60-76 / Edge x05 series. The transfer speed could be very slow, at least with eTrex20(x). Therefore it can be a good idea to use an external card reader for this.

View in BaseCamp

To plan routes directly on your desktop, it is also possible to use the maps in Garmin BaseCamp. This software is free. Once installed, insert an USB-Stick, or other external hard disk, create the Garmin subfolder described above and copy the files to that location.

Use in Garmin BaseCamp

Not just for your GPS: The usage in Garmin BaseCamp is also possible.


What is "md5sum"?

On every download page you can see a string like "md5sum: xxxxxxxxxx". A md5sum is a calculated hash value of a file and represents a distinct fingerprint of that file. So in our case you could verify whether all data of the map image were transfered correctly to your computer during the download. There are a lot of freeware programs out there to do this, for example this one. Once you have computed the md5sum of your downloaded file, it should be the same value as on the page.

If you have trouble to get the map running on your GPS or BaseCamp, you can sent me a message. I will try to help.
