As you don't specify which model, if Edge 820 or Edge Explorer 820, I made both ...
This is a Patched Firmware (JNX + Unlocked Maps) for Garmin Edge 820 ver. 11.20
Since the Garmin Edge 820 (HWID: 2530) does not have the GSV and falls into category 2
MSV: Yes, GSV: ---
In this case the Patched Firmware guarantees the correct reading of Unlocked Maps, including NTU and TOPO Maps with CP 65001.
The Patched Firmware guarantees reading of BirdEyes JNX images too.
Be sure to remove All BirdEyes images eventually present on Device before apply Patch
BirdEyes images can be restored AFTER flashing new firmware
Also, in this case the "patched" Firmware can be loaded through the normal update procedure via WebUpdater
Changes made from version 11.10 to 11.20:
- Fixed a crash that could occur when riding with a cadence sensor.
Changes made from version 11.00 to 11.10:
- Added support for 12-speed shifting sensors.
- Fixed data field issues when using a shifting system with no front derailleur.
- Fixed issue where radar would not automatically reconnect after being disconnected for more than 2 minutes.

- Made several improvements to the Sensor Details UI for Vector 3 power meters.
- Fixed average power balance data field not working correctly.
- Added the option to choose the radar alert tone.
- Fixed an issue where setting the device language through Garmin Connect would result in the language defaulting back to English.
