Hi, we do not support downloading gmapsupp.img file(s) directly because we need to let the user select the areas to upload to gps devices.
But it is possible to create gmapsupp.img from our detailed imgs - at least - with sendmap.
Our imgs are nor corrupted (we're using them on windows) nor encrypted (they are free). We've got no any mac experience, so we can't help why the conversion fails. But googling a bit I've found this page. It states that no conversion is required for BaseCamp for Mac because it can import gmapsupp.img.
Hope, this helps.

How would it be possible to install a gmapsupp.img, covering approx. the territories of Austria, Slovakia, Hungary, Croatia and Serbia, on an Garmin Etrex GPS device from OpenMaps maps?

Is there direct download of this file available?

If the gmapsupp.img file must be created, how would I do that with MacOS, Linux or other BSD computer?

So far I downloaded OpenMaps_OmpCEHiking.zip, unzipped and tried to convert to Garmin BaseCamp gmapi. However the conversion fails:
--
volker@leo:garmin$ ./gmapi-builder/gmapi-builder.py -t OpenMaps/60product.tdb -b OpenMaps/60product.img OpenMaps/*img -o gmapi-out -v -v 2>&1 |less

...
OpenMaps/05010018.img is not a Garmin IMG file, or it is encrypted.

Any help is much appreciated.
