How to get FREE maps for your Garmin GPS

Step 4Copy the map to the GPS

Copy the map to the GPS
By hook or by crook we've got the SD card mounted as a drive. Now, before going further, a quick warning: Before copying your first map up, you probably want to copy down the existing map before you overwrite it!

The map is a file called GMAPSUPP.IMG and it lives in the \Garmin folder. You can ignore any other files that may be present.

So the order of ceremony is something like this:

1: Copy the existing GMAPSUPP, your old map, to your PC so you don't lose it. Stick it in a folder with a sensible name!
2: Delete the GMAPSUPP on the SD card / mounted GPS.
3: Copy your new map IMG up to the card/GPS's \Garmin folder.
4: If it's not called GMAPSUPP.IMG, rename it now.

Finally, restart your GPS and your map will be ready for adventure!
