Map land cover clutter is terrible

So first day out with my new Edge 820, moving up from an Edge 520. Started the ride, and as soon as I got near the first path, I saw it disappear in a green blob of what I assumed were "trees" or "forest". I've been now playing with settings (visibility, zoom levels for each element, detail, etc.) and have NOT found a way to turn off the useless clutter caused by the green background. It basically makes paths invisible.

I tried setting "Land cover" to off, to no avail. On my Edge 520 I was using OSM, which had beautiful rendering compared to Garmin's own maps - see the side-by-side comparison (I've marked the location of the path's start so you can see the difference... which is obvious anyway).

Anyone have any idea on how to turn the Green Blob off?

Have you tried disabling one or more maps?

Yes, I have, to no avail. The base map is large-scale only, and DEM & routing maps have no land cover detail.

I've posted about this previously. Wooded areas are dark green and trails are indicated by thin black dotted lines that are nearly invisible against the dark green. IDK if this is a property of how the 820 chooses to display the map or if it's a property of the map itself, in which case using a different map may help. The workaround posted by another user and that I'm using is to lay out a course over the trails in question, set the color for the trace, and then set that course to always display on the map. This is definitely a pain in the butt.

Thanks for the insight looigi. I've figured out an in-between solution: the routable maps & DEM maps are two individual files, while the topo/cycling map (1.7GB) has the actual graphical content in a third file. I've replaced this third file with the OSM I was using on the Edge 520 (simple copy & paste), and tried starting navigation to a POI on the 820. The result? The routing calculation went fine, and the resulting pink track was overlaid on the clear, uncluttered OSM graphics. Best of both worlds!

What was the file name of the third file? Did you delete the third file from the 820 and then rename the file file from the 520 to match?

I think you'll find that the DEM is the Digital Elevation Model and is used for calulating elevation profiles, so should not be the cause of your problems.

It's a property of the map. The Garmin maps have a "style sheet" that indicates how different types of things are displayed. Yes, a different map might help.

* INTL Standard Basemap, NR -> gmapbmap -> global basemap (no routing info)-> keep enabled.

* Garmin Cycle Map EU 2015.10 -> gmapprom -> detailed map for display and routing. The "Garmin Cycle" map has detailed image and routing data. (You need this or an equivalent map for navigating).

* Edge DEM Map EU 2014.10 -> gmapdem -> elevation database map -> enable if you want to pick a generated route based on elevation.

* Garmin Geocode Map EU 2015.10 ->gmapgc -> addresses to coordinates map -> enable if you want to select an address/etc to route to. Otherwise, it doesn't matter.
gmaptz -> time zone map -> keep.

These are the names for the European maps (maps for other locations will have similar names).

The geocode (addresses) information can be combined with the detail/routing map. That's how Garmin does it with the "City Navigator" maps.

okay - first thanks for this post! ...I actually just downloaded an openstreet map that I used on my 520 and was going to try to figure out how to add this to the 820. I wondered if I could drop this into the newfiles folder and allow the Garmin to process and add as another map option and if I could then un-select the garmin open cycle map and select the new openstreet app. (leaving the elevation and other maps enabled.

If that doesn't work i can backup the current map and replace with the new openstreet one.

OK, so here is a quick step-by-step:

1. Backup the files gmapbmap.img and gmapbmap.sum from your Edge 820 to your computer.

2. Copy the gmapbmap.img and gmapbmap.sum from the Edge 520 to the Edge 820, on the same location - they are already in compatible format so no need to drop into NewFiles.

3. Enjoy!

I've tested routing today, searching by POI, etc. and everything works fine. All the routing capabilities, with OSM maps instead of Garmin's.
