After some research, I came across the fact that you can use the developer tools from the popular (in Germany) OSM-Freizeitkarten website to create a Morocco OSM map.

I downloaded the developer tools and installed it on my MacBook. I had problems until I installed the correct JDK (Java Development Kit).

After successful installation it's quite easy. You have to enter the following commands, which I have summarized in a file named morocco.sh:

#!/bin/bash
perl mt.pl
create 6504
perl mt.pl
fetch_osm 6504
perl mt.pl fetch_ele 6504
perl mt.pl join 6504
perl mt.pl split 6504
perl mt.pl build 6504
perl mt.pl gmap 6504
perl mt.pl gmapsupp 6504
# DELETE OLD MAP!
# rm -r “/Users/[USER]/Library/Application Support/Garmin/Maps/Freizeitkarte_MAR.gmap“
# cp -R /Users/[USER]/Downloads/fzk-mde-garmin-LATEST/Freizeitkarte-Entwicklung/install/Freizeitkarte_MAR_en/Freizeitkarte_MAR.gmap “/Users/[BENUTZER]/Library/Application Support/Garmin/Maps/“
# COPY TO GPS DEVICE: cp /Users/[USER]/Downloads/fzk-mde-garmin-LATEST/Freizeitkarte-Entwicklung/install/Freizeitkarte_MAR_en/gmapsupp.img ZIELVOLUME/Garmin/MAR_en_gmapsupp.img 

The batch file morocco.sh can be started on the Mac with "source morokko.sh". Then you have to copy the maps to the right folders. The corresponding commands are commented out. I am already more familiar with the appearance of the Freitzeitkarten than with the maps listed below. You can create up-to-date maps in this way.

If you can not cope with creating the maps yourself, you are welcome to contact me. If I still have everything installed and it still works, I will like to create a current OSM map for you.

OSM maps are also available for download here.

I downloaded the map gmap_Morocco_VFP.zip for Garmin BaseCamp on MAC OSX. Unpack the ZIP archive and then install the file OSM+VFP Morocco.gmapi by double-clicking with the Garmin MapManager. Important! This map does not contain the data for Western Sahara, which can be found in the file gmap_Western-Sahara_VFP.zip!

Then you have to download the file gmapsupp_Morocco_VFP.zip for the Garmin GPS device (the data for the Western Sahara can be found at gmapsupp_Western-Sahara_VFP.zip!). Unpack the ZIP file. Attention! The file In the ZIP files are always named gmapsupp.img! The file gmapsupp.img must not be renamed for use in Zümo 660 for example. The file is copied to the Zümo's MicroSD in the Garmin directory. If there already exists a file with this name, then it must be renamed or an extra MicoSD can used for the new map.

You can also download maps for Morocco from http://garmin.openstreetmap.nl/. Here you can manually add additional areas (Perhaps you'd like to add some additional tiles?), so that you can get a map for Morocco along with the data for the Western Sahara.
