I love hiking but I'm not used reading maps. Therefore I bought myself a garmin GPSMAP64 GPS. In the maps challenge I saw an instructable of how to make maps for a garmin gps this is a very well written instructable and it made me think to write my way of uploading maps onto my GPS. This will be a very short instructable because it's really simple to do.

You only need your GPS (ofcource) the openstreetmap website and an usb-cable to connect your GPS to your Windows PC, Linux computer and I'm pretty sure it will also work on IOS or any other operating system.

Step 1: Creating Map(s)

In the picture above all steps are framed in yellow. First go to openstreetmap

choose your map type (I use generic)
choose a predefined country (countries are sorted by continent)
If you like to add some other regions you can check the checkbox.
Enter your e-mail adress.
Check the tiles that aren't in blue if you like to add them to deselect press them again.
Click the build my map button.

Step 2: Download the Map

After clicking the button you get a message that you will receive 1 mail directly and a second mail when your map is generated

In the first mail you get a tracking link where you can see how long you have to wait. (see pictures)

In the second mail you get a link to download the map. (4th picture) Click the link in that mail.

Step 3: Uploading the Map

When you have clicked the link you go to a page where you see all generated files.

Download the file osm_generic_gmapsupp.zip
Connect your garmin to your computer
Open the garmin gpsmap folder.
Go to the folder garmin
Rename the gmapsupp file to the name of by example the region
unzip the downloaded file to the garmin folder
You're finished now. Don't rename the gmapsupp file because this is the one that will load.

Step 4: Conclusion

In this very short instructable I showed you a way to easily replace the maps of your garmin by openstreetmap maps. This way you can freely use very detailed maps of any region you wanna hike.
