How to remove symbol from being displayed on device

How does one remove the symbol from being displayed on the map on a Etrex30x?

The route i have has roughly 190 waypoints and each one shows a blue flag, needless to say, in a two mile long hiking trail it's hard to see the path.

I'd like to only be able to see the colored route without the symbol, is this possible?  All the settings i see in basecamp that makes one think this is possible do nothing.

Thank you, Mark
