Even though it is better to download EPO data from MediaTek (as described in my above post), it is still possible to download it also from Garmin.
For whoever may be interested, here is the command to invoke from Terminal (Command Prompt).
It does essentially the same what original Garmin Express does.
It however requires curl, sed and base64 tools. All are typically Included in Linux or Unix systems.
But Windows contains only curl, so sed and base64 must be downloaded separately:
sed for Windows
base64 for Windows
But I have only posted the above for educational purposes. For regular user, the simplest way is to just use EPOupdate tool and forget about these magic spells.

Code: Select all
curl "https://api.gcs.garmin.com/ephemeris/cpe/mtk/segments?segments=28" | sed -e "s/^\[{\"gpsHours\":[0-9]*,\"data\":\"//" -e "s/\"},{\"gpsHours\":[0-9]*,\"data\":\"//g" -e "s/\"}\]$//" | base64 -d > EPO.BINBut Windows contains only curl, so sed and base64 must be downloaded separately:
