Heads up that Garmin just released a new software release for most units (no updates for the GLS10 Livescope module)
From an echoMAP 93svUHD perspective (unit I have) I didn’t see any huge updates:
Changes made from version 16.10 to 17.10:
Added Mercury engine page and alarms.
Improved presentation and review of ActiveCaptain Community POIs.
Added support for momentary switches and a configuration page using standard NMEA2000 switch PGNs.
Fixed an issue where trip data was being reset on power off.
Improved software updates from ActiveCaptain.
Expanded allowable values for dynamic lake level.
Added ability to auto align vessel icon to heading or COG based on speed.
Updated magnetic variance models.
Fixed issue with split frequency sonar gain controls.
Other improvements and bug fixes.
