It sounds like you perhaps have downloaded Garmin's City Navigator Morocco which is a roads-only mapping.

I certainly cannot recommend Garmin's Topo Maroc v2 maps. The road numbering at zoom out scale reverts to the pre 1980 numbering system, there's often little difference shown between footpaths and pistes, placenames aren't shown at various zoom settings, and the routing is screwed by roads that aren't linked.

As a simple example of the last item the attached image shows what happens when you route Marrakech to Ouarzazate via Telouet. The Telouet road isn't linked to the N9 as it crosses the Tizi n'Tichka so it routes you the only way it knows.

The second image shows how I would set up the same route in Mapsource using Olaf. Yes it needs some extra clicks with the routing tool.

It seems to me that there is too much focus placed on 'turn-by-turn' routing.
Unless you have half decent mapping, (and most are flawed to different levels), it is a great deal more enjoyable to:
Create waypoints at strategic places,
Set your sat nav to 'direct routing'
Display the compass page set to CDI

And ensure that you have data fields showing:
'Distance to next'
'Heading'
'To course'
'Trip odometer'

This not only frees your ears from daft instructions but lets you enjoy the scenery around you and the riding which is what you went there for!
Happy trails.

I can honestly say I have only had 1 problem in 4 trips with OSM Routing when it sent us down a 1 way street in El Jadida, otherwise for turn-by-turn routing OSM has been fine in Morocco

I've also had some pretty decent turn bu turn routing on piste via OSM. However for off road routes I don't generally use the routing as I find it automatically re routes and takes me away from where I want to go (this maybe down to my ability). For off road routes I convert the route I've planned in Mapsource into a track. That way my chosen route doesnt change from my plan and no annoying directions

I don't remember which Garmin map I had, but whatever it was, it was completely and utterly useless once I was away from the coast. I've used Garmin and OSM maps in plenty of other places with no problem, but in Morocco I ended up just turning the GPS off altogether.

Depending on where you're going, you don't really need a GPS as long as you have a paper map, most of the roads are pretty well signed.

Just back from our first trip to Morocco, and took both Garmin with Olaf and OSM in my cheap tablet. Didn't use either very much when on tarmac, but of the 2 we found OSM far better for pistes and general off-road stuff. The detail was greater, most of the visible tracks (on the ground) were in the database and made detailed navigation very easy. The downside of this is that you have to be zoomed in quite a bit to get the track displayed, so it's easy to lose the "big picture" and focus too close to the vehicle. Our technique was to rely on the (old fashioned) compass and odometer for general progress and check the electronics when we reached critical points or had to divert because of washouts or other barriers. Like Tim and Bertrand above, we went for the views and the ability to go where we liked, so knowing where we were all the time wasn't a priority.

Works well flying an aircraft, but not so useful on the ground unless roads are straight and few in number.

Couldn't agree more. I just need to know I'm headed in roughly the right direction and more often than not I use the position of the sun as an indication.

But not in the UK—not enough sun

Hi Tim:

You are correct, that is the map that I purchased. I used it for the first time today, for guidance on a ride from Chefchaouen to Ifrane. So far, I'm very happy with the routing performance, especially through the city of Fes. But, it's still too early to provide a carefully thought out evaluation of City Navigator Morocco.

Bertrand:

I must respectfully disagree with you. I spent 40 years working as an aircraft pilot, most recently delivering new production aircraft from the factory to all 7 continents (including Antarctica). To heck with 'waypoint' navigation, that went out of fashion in the aviation world years ago. Contemporary aircraft nav systems allow the pilot to enter the origin & destination, then select the desired airways to follow... the FMS then populates the flight plan with all the waypoints along the selected airways.

One of the most significant safety problems the aviation world faces today is fixation on navigation system displays (vs. having one's head up and looking out the window). I spent years trying to minimize this risk in aircraft, including one in which I did the design and specification of the flight compartment (photo below). The last thing I want to do is put myself at risk when riding the moto as a result of needing to spend time 'head down' monitoring a HSI-like CDI on a motorcycle (HSI = Horizontal Situation Indicator, CDI = Course Deviation Indication)

Exactly. I much prefer to keep my head UP, looking at the scenery and watching out for other traffic, than keeping my head DOWN looking at a navigation screen.

Voice navigation guidance is a significant safety benefit, because it eliminates the need to have to look down and monitor the GPS screen. When a turn or course change is needed, it is annunciated via the Bluetooth connection to the helmet speakers.

I retired to get away from this, not to spend more time looking at similar displays on a moto:
