ilovecornfields Posted November 27, 2022 Report Share Posted November 27, 2022 Apparently my GTN750 decided it doesn’t want to display my Jeppesen charts anymore. It’s a feature I never used, but now that I don’t have it I want it back. Anyone run into this before? Thought I would check before I spend a long time on hold with Garmin only to have them tell me to talk to my avionics shop (which doesn’t often have an answer). Maybe @TrekLawler is around? The screen says “Disabled 10-NOV-22” but doesn’t say how or why. Quote Link to comment Share on other sites More sharing options...
PeteMc Posted November 27, 2022 Report Share Posted November 27, 2022 You said "...It’s a feature I never used..." so did you keep the Chart Data current, or only the Nav Data up to date? If the Chart Data is not current, I would expect the GTN to not show you the old chart. Quote Link to comment Share on other sites More sharing options...

PeytonM Posted November 27, 2022 Report Share Posted November 27, 2022 It does for a couple cycles, I think. Quote Link to comment Share on other sites More sharing options...

StevenL757 Posted November 28, 2022 Report Share Posted November 28, 2022 Have your shop fully update the firmware/code on your 750, then after a restart, have them re-apply the JeppView unlock SD card and it should restore the Jepp chart functionality.
