Hi OLDUN,
Paper maps are good, along with the obvious michelin 742, look at the insight one it's 1:800,000, less terrain detailed but much better for road mapping, there's also a rough guide one.
Personally I wouldn't bother with Morocco maps from Garmin or TomTom, they just don't cover the bottom half of the Country well enough. A mapping gps and Olaf maps work well enough, plan through mapsource/basemap. You'll probably know to look at the Morocco Overland website for lots of info and upload tracks.
As phones signals are poor in the south of the Country, you could always buy a local pay as you go sim card, though signals can also be poor. Sat phones are great, just be wary, police are cracking on them due to high criminal usage.
"This time dont want to worry about getting lost /where am I. Just want to do all the track routing in advance and enjoy the remoteness of the journey."
Sounds great, have a good trip, Cheers Mark
