Turn off display of route markers...

Most users simply use a much smaller or invisible custom waypoint symbol for the blue flag/blue pin.

So on my GPSMAP 66i, how do I do this?

Viewed as a Route, the pins appear. Saved as a Course and viewed, no pins appear. It's exactly what I want from a route.

Convert the route to a Course.

That is what I want for the display of a route.

So how do I make that built in blue pin smaller/transparent, etc. for a route on my device?

Thanks in advance.

Turns out, that the course appearing without markers is a side effect of making a course from a route. If you make a course instead, it has markers like a route. Inconsistent at best.

Regardless, getting something like the course without large markers for a route and vice versa is the goal.

I don't have Basecamp, but here's what I think the problem may be. A "route" is typically defined in the hiking world as a planned path one intends to take. It is usually a highlighted path on mapping software or a mapping website. A "route" in the automotive world is the path provided for you by the GPS software based on your destination input. The hiking route is passive navigation, the automotive route is active navigation.

I think you're using the Basecamp route (hiking) and then sending it to the 66i as a route (automotive). 

A quick fix that might work is to synch your device with Garmin Express. I don't know why, but it has removed pins for me in the past. You could also, after saving the Route as a Course, convert the Course to a Track. The saved track represents a saved hiking route.

What you really want to do in the future, is export the Basecamp file as a track, not a route, if that's possible. If not possible, you could try to import the Basecamp route into the Explore website, but do so as a track.  Then, synch the track to the 66i.

If you actually want the active navigation of the 66i Route Planner, then you are stuck with the pins.

I don't ever use my device for "automotive" activities. Only "tramping" (as we call it in New Zealand, "hiking" for the rest of the world - go figure! ). In BaseCamp all my routes and tracks have the recording activity type set to "Hiking." On my device, the default profile is set to "Hiking". If I look at the routes/tracks on device, they show as "Hiking" when viewed in BaseCamp.

Courses don't seem to have an "activity" like routes and tracks.

Then tracks, whilst they can have more points (i.e. a more finely grained "breadcrumb" trail), and display without the dreaded pins, when used in the field (empirically determined) if you go passed a track point when navigating, the GPSMAP 66i does not reroute to the next point like it does for courses and routes, and insists you go back to the missed track point!!

I think it's time to make a change request.

Thanks to all for responding.
