People riding MC like routes on twisty roads but don't like the Zumo display being cluttered with flags and the headset announcing route points not needed. We used to be able to prepare routes in MapSource with viapoints on intersections. That would prevent flags and announcements for the Zumo 66X and Zumo 550. With BaseCamp that does not seem to be possible anymore. We had a discussion on that on the Zumo Forum from where I quote:

I noted the suggestion by Dave that it could be a problem with BaseCamp. I normally make and modify my routes in MapSource (taking advantage of snap-on to intersections) and then copy/paste the route to a list in the BaseCamp database from where I download whatever routes I want to the Zumo.
I made a test by downloading the route to the Zumo directly from MapSource bypassing BaseCamp entirely. Guess what - no flags except my one intentional waypoint.
It does appear that BaseCamp does some strange things to route points, both via and shaping, that cause flags to appear on routes in some random fashion on the Zumo 66X. I really like the folder/list structure of BaseCamp and would hate not being able to use it.
I plan on raising this concern also on the Garmin BaseCamp Forum.

I attach two screendumps, one with the route downloaded from BaseCamp, the other from MapSource. BaseCamp is V 4.1.2.
Please make BaseCamp consistently honor the intersection facility for non-announcements when downloading routes to the Zumo 66X/550. If BaseCamp would also allow the snap-on facility then I could drop MapSource entirely.
