This is another example of "not Garmin's problem".

Garmin won't fix it. It's not really Garmin's responsibility.

Understanding why is kind of important for using these devices for navigation effectively.

I removed the "path" and added the fence.

Garmin wants us to hop a fence and ride the drainage canal.

Next time, include the Google map link!

Keep in mind that the routing favors the shortest distance.

The maps that come with the current Garmin units are Openstreetmap (OSM) maps. Openstreetmap is a publicly-maintained map database. One reason Garmin uses OSM maps is because they are cheap (free) and Garmin doesn't have to deal with the expense of maintaining them. Another reason to use OSM is that the OSM maps contain cycling-specific features that commercial maps don't have. Google has some of these but other companies can't really use Google's maps (outside of a limited way).

As far as the OSM data is, that route looks OK (as far as the world the map knows about, there is no fence or ditch).

The problem is that the map doesn't match the reality as accurately as it should. This a fundamental problem with maps: maps can't match reality exactly.


No one would be able to determine the quality of that "cheat route" unless they went and physically surveyed it. No commercial company is going to do that (it's way too expensive). People who live in the area and update OSM might.

The commercial maps ("City navigator") that Garmin sells wouldn't have the bike path (or the ditch or the fence).

The "track" (the path) is shown on OSM but not on Google maps. That Google maps doesn't have it might not be a good thing either: people might have legitimate reasons to want to get to a road at that location.
