Garmin gpsmap60/62 series where you can load in public source maps and import/export routes tracks etc betweem gmaps and gearth. Also Chris Scott's Morocco overland and Sahara overland guides with waypoints and routes, and ressources from Horizons Unlimited "the hubb" plus http://www.island-olaf.de/travel/marokko/gps.htmlVery enjoyable video. We will ferry across from Spain (driven 4 continents and 22 countries in last 3.5 years; damn doctor slowed us down in 2019) to Morocco in early Feb. 2020. What GPS system did you use in Morocco and is it good in the Western Sahara?
(We used a Garmin in India/Nepal/India but finally left it somewhere because it was next to worthless and relied on people giving us directions. Since then have used our phones and Google maps.)
Thanks, Tom
