Navigation arrow color changed to green?

I have the same issue. It’s frustrating. 

I have the same issue on my Edge 820. I hope that they can fix this soon.

I have the same issue on my Edge 820. I hope that they can fix this soon. (or would it be possible to go back to a previous version of the software on my Edge? The last version was indeed a lot easier to navigate...)

Same here on my 820. Large portions of the map are green, so is the colour of the course and the arrow. I lost the track while using my gps ... the irony... 

What maps do you have on the Edge? If they are they are the standard Garmin maps, what version and what regions do they cover?

in my case it's the standard garmin maps which came with the 820. I have never upgraded these manually but maybe they have updated together with installing the 12.10 version of the software. Where can I see what version/regions of the maps I have?

On the 820 go to

Settings -> Activity Profile -> name of profile you are using -> Navigation -> Map -> Map information

My edge uses multiple maps apparently : 

- INTL standard basemap, NR

- Garmin Cycle Map EU 2017.20 

- Edge DEM Map EU 2014.20

- Garmin Geocode Map EU 2017.10

I am using a Garmin Edge 820 with software version 12.10

I have the following maps installed:

Garmin Cycle map EU, North East, 2019.10

Garmin DEM Map EU 2017.20

Garmin Geocode Map EU 2019.10

Garmin Cycle Map EU, South West, 2019.10
