custom maps folder?

When you connect the 520 to a computer there's a folder in Garmin/ called custom maps. Does anyone know what this is for? Can I load in 2 or 3 different maps for example then select from the Garmin which one I want to use depending on my location?

    I had a go at overlaying a map jpg onto google earth then exporting the kmz file and putting it into the new files folder as well as the custom maps folder, but it's not displaying not he device, maybe i didn't go through all the steps correctly but it would be good to know if the 520 had this functionality.

    map location

    in the main garmin folder backup your gmapbmap.img file. rename whatever new basemap you want to use to that name, and locate in the same directory. i've been advised to keep the map file to around 50mb to work with available 520 memory. more info here:

    google open street maps for garmin 520 and you'll find youtube videos on how to do it

    No - my question was about the function of the Custom Maps folder. I have openstreemap installed and renamed for my cycling area, it works fine, but the custom map folder Alan says is used to add the graphics of a scanned paper map to the device display for a certain area, via geolocating on Google Earth. (image overlay, then create a kHz file from this and upload to the device) - if you follow the link he provides it will clarify this. Not sure if its really implemented yet on the 520, or if I just haven't had enough time to play around with it properly yet......

    Anyone tried and succeeded to get a scanned custom map working on the 520?

    I succeeded yesterday to display a raster map on my Edge 520.

    I read that it is possible to do that with GIMP and Google Earth (https://support.garmin.com/fr-FR/?faq=cVuMqGHWaM7wTFWMkPNLN9) but i did it another way.

    With MOBAC (Mobile Atlas Creator) I was able generate a "Garmin Custom Map" KMZ file from various mapping sources (including USGS, IGN,...). https://mobac.sourceforge.io/

    The KMZ file was then dropped in the CustomMap folder of my Edge.

    At the next startup, my raster map was displayed on top of my vector OSM map.

    It seems that the zoom level can hide or display this new layer, and the scrolling can be a little bit slow depending of the size of the map. But it works Smile
