My Garmin 530 has big disc image files. What is that?

I just bought the south America cycling map and added to my Garmin. I checked the "garmin" folder and there are several "disc image files" on it, so now I have little space. Is that possible to uninstall the US map? Can I delete those image files?

    They aren't "disc image files'. They are map files.

    You could delete the North American map files, but Garmin Express will probably want to reinstall them.

    Hi dpawlyk. Thanks for your help. The only thing I find weird is that there are 5 or 6 of those "disc image files" and they all have coded names instead of "US map", "South America map", etc, so I don't know which one is the US one to delete

    The map data is split into three files.

    Gmapprom -> image and routing.

    Gc -> geocoded info (address lookup).

    DEM -> elevation data.

    There are other small maps files (timezones basemap, etc).

    ==========================

    If people want maps for a place they vacationing at, they might be better off using the free openstreetmap maps that are available free. Since they can download a map for just the region they need (a much smaller file) and they can always get current maps. People don't usually need a whole continent and you have to re-buy the maps from Garmin to get updates (the Garmin Cycle Maps are based on openstreetmap data)..
