Directions links on Map Marker field don't work in a view

I get a lovely map of trailheads, using the Map Marker field (see attached graphics). Unfortunately, the direction links point to the site's own home age. <a href="/" target="_top">To here</a>

Google maps will actually provide directions to a latitude and longitude, so I'm thinking that this should work.

The directions links work successfully when the field type is Geocoded Address Marker.

Would love to be able to provide directions to trailhead parking locations.
