Garmin Terrain Warnings

[Skymac]

Is anyone an expert in reference to the GTN750/G500 Terrain system? Maybe a secret system setup menu that allows you to customize the altitudes at which you get alerted for terrain and obstacles hazard.

I routinely have to fly low for work, and I really like having terrain enabled, mostly for obstacle warnings but I often find myself turning it off because it will not hush! I would think the helicopter guys have a lower threshold on warnings but maybe I’m wrong. It would be nice if I could totally inhibit the terrain portion and only leave obstacles enabled.

There is a different set of warnings for helicopters. But I think that is only available to be activated by a dealer for a helicopter due to the STC.

I have a 650Xi, and just did the Garmin training (upgraded from non-Xi), and there was nothing about modifying the alert altitudes.
