Has anyone encountered an issue after upgrading a GDU4xx from version 8.72 to 8.81, and then have a GDL39-R stop reporting traffic? I see from the archives (Apr 2020) this was an issue in an earlier version of the GDL39 software (4.9), and fixed in 4.91.
I recently performed the GDU4xx upgrade to 8.81 and I believe this is when the RS232 Port 1 on the GDU4xx stop working (red x). My backseat passenger using a connected iPad reported a firmware upgrade is needed on the GDL39-R. I am curious if anyone else has seen this issue. I have a trouble ticket (so to speak) with Garmin.
thank you
