Here is essentially the same area of the same chart in the Navionics web viewer.

The markers are much more visible (black rectangles) and have a color square on top of them to show red-top vs black-top type of navaids to indicate which side is safe passage.

It's a simple change, and the information used to be on the Garmin charts. So we're trying to get them to fix this issue. They seem to be listening, but it's taking some time to get the results published.

I also asked them to make the 'suggested route' lines a bit easier to see, perhaps a different color or make the line thicker as the current implementation tends to get lost among the depth contour lines.
