Unable to Create a Course Using a Certain Road
When creating courses in your Garmin Connect™ account it is possible that the course will not allow you to use a certain road. This occurs when using Google Maps for the course creation.
Currently the Google Maps option in Garmin Connect only uses Walking for directions. This will only allow you to create courses for places that you can walk on.
You can use the OpenStreetMap option as an alternative when creating a course which will allow you to create the course on these certain roads.
To switch the map to OpenStreetMap:
Sign into Garmin Connect from a personal computer.
Select the Arrow Icon in the upper left corner to expand the Navigation Bar (if it not already expanded).
Select Training & Planning.
Select Courses.
Create a new course or open an existing course.
Select the map option from the upper right corner of the map.
From the drop down select OpenStreetMap.
You will now be able to create your course on roads that allow bikes in addition to walking.
