Install a custom Garmin map on your device

Installing a custom Garmin image on your device is easy:
  1. connect your Garmin with a USB cable to your computer (or your SD card). You will see the Garmin device as a disk/storage in the explorer
  2. download the zip file and open it. There is a gmapsupp.img file inside
  3. copy the gmapsupp.img file to your Garmin device in the folder /Garmin with the explorer (Windows) or finder (MacOS). You can do this also on the command line on Linux/FreeBSD.

That's all. You are done! See also Installing_the_map_onto_your_GPS

Garmin internals

Routing is enabled for the Garmin maps. Depending on your device, it is possible to store more than one Garmin map (or with different styles) on your Garmin.

By default all generated Garmin maps from OpenStreetMap data will use the code page Unicode (UTF-8). However, some older devices don't support Unicode and some new devices have a broken DRM firmware ("can not unlock map"). In this special case please use the latin1 variant. Garmin SRTM extracts use always the ASCII/latin1 character set.
