Add maps to Garmin etrex 10

[KaniJonas]

So I'm vcompletely new to gpses and now struggling with adding a detailed map of my area to the device.

I have mapsource installed and downloaded a map in .exe format from openstreetmap.

I selected it in mapsource and sent to device and it said it was sent sucessfully.

But on the device I just see the base map, even if I go to my area and zoom in.

 

Am I missing a setting or something?

An etrex 10 does not have enough internal storage space (and no SD card expansion) to hold a detailed map except for a very, very small area.

Ah, not so fast, grasshopper! I have an Etrex 10, and I have detailed maps on it that cover all of Tucson, where I live, and quite a bit more. And it only takes up about 4mb. I found a website that has maps for Garmin's smartwatch fenix, but it works just as well in the Etrex 10, and they're free and legal. Here is the website to peruse: http://www.gmaptool.eu/en/content/maps-garmin-fenix

 

Here's the process:

1. Download the region you want from the website above and unzip it.

2. Install it in MapSource by running the install program in the unzipped folder you just made.

3. IMPORTANT: Connect your Etrex 10 to your computer and COPY ALL of the files on it to some safe place on your computer. If something goes wrong with the map procedure, you have backup files!

4. Using MapSource, transfer the areas you want to the Etrex 10. Make sure you leave 3-4mb free on the Etrex so you don't get "memory low" warning while using it.

5. Here's another important thing to know: The Etrex only recognizes and displays its basemap (gmapbmap.img). The map you just loaded is called gmapsupp.img. In order to display your new detailed map, you need to delete the gmapbmap.img file, then rename your gmapsupp.img file to gmapbmap.img.

 

The detailed map is pretty primitive, showing only lines for roads, but all the roads are there, plus trails! It's really made my cheap little etrex a very capable machine.
