Does anyone know what format of raster images works with Orux Maps? I tried to export maps acc to Orux Maps specs from ArcGIS 10.1 in every possible format (Geotiff, GRID, jpeg2000...), loaded with a .tfw file and it always displayed a colorless tile.
Note: your files need to be be geo-referenced (tfw filesfor tiff, .pgw for png)
also a useful link is
