Zoom > 11 works fine with a small(er) map canvas (e.g. on a laptop computer).

The issue is probably due to QImage or memory size limits (has to be checked)...
If QImage`s limits are exceede, no rastermap is produced which is why gdal_translate / gdalwarp / gdalinfo does not find input data. Here an errorhandler is needed...

One solution could be to limit image size to Garmins limits of 100 megapixel across all custom mps on the GPS unit...
