G3X pitch trim indicator

I need to add the pitch trim indicator to my PFD (GDU 470 touch). When in config mode, I have green check marks in all the right boxes except "PTRIM". It just skips over this box while scrolling through the various points. It won't let me "click" on it.

I tried the search function of the online manual for all kinds of pitch trim searches. All I can see showing up is how it works.

If your system has a "PTRIM" entry in the Device List on the System Information page, it means you incorrectly enabled a pitch trim GSA 28 servo in the LRU configuration.

While you might have a typical pitch trim motor in your plane, you probably are not using a separate GSA 28 servo for pitch trim.

Make sure that both roll and pitch trim servos are disabled on this page.

I realize now why I didn't see this post in the "glass cockpit" sub forum. ........I put it in the wrong place. lol
Thanks Steve. I'll check it out.

Well.........that didn't fix it. I still don't have trim indicator on the PFD.

The trim position sensors are set up in the Engine & Airframe menu (Icon)

You will need to enable/calibrate the device that's connected to one or more of the discrete inputs to the GEA 24 or GSU 73.

See page 35-175, Section 35.4.32.16 of the installation manual.

You then will need to enable the trim display on PFD/MFD --

See page 76-77 of the G3X Pilot's Guide.
