New to OSM, question about getting OSM onto my Garmin

Hello, and great looking suite of tools!

Long story short, an oops on my part vaped my Garmin unit. I was writing an OpenSUSE USB image to a thumbdrive, and had the wrong device. I was able to reinstall the firmware but now need maps. I have been restructuring my devices and choices in devices to play better with OSS friendly stuff, so I am not going here to be cheap. In fact I would rather pony up the $80 for maps to the OSM gang.

The crux here is if the 4000MB data blob I found here:

can be blasted directly onto the unit rather than needing an SD card. Not that this is a huge deal, but rather semi-important as to the fact I like the MP3 playback feature and having one SD card slot would make that hard to do both, mapping and audio playback. But TBH, there are always more than one way to skin a cat :stuck_out_tongue:


Oh, is there a donation page? If this all works out I would love to just donate what I would have paid Garmin for the lifer map service to OSM.

What model Garmin are you using?
If your Garmin has enough internal memory, then yes, you can install the maps on that. Just create a folder named “Garmin” and copy the gmapsupp.img file to it. Though I don’t know of any Garmins that have 4GB of internal memory?
Or you could get something like a 8GB or 16GB SDHC card (now fairly cheap), that should have plenty space for the maps as well as MP3s.

There is a donation page at
You could also contribute to OSM by surveying and mapping your area, to help make the map better.
