I just discovered a glitch with my G3X update. Since updating to 8.6 and installing map data base updates, I can no longer get the radio frequencies to "Auto Transfer" to my SL 40 Radio. I spent 1 hour on the phone with Garmin and they asked me to check the MFD COMM PORT CONFIGUARATION. And this is what they asked me to set it to after several failed attempts:

RS-232 1 is set to Garmin VHF Comm
RS-232 2 is set to GTX TIS-A In (I believe this lets my Zaon traffic device communicate with the G3X).

I tried this but it still wont transfer the radio frequencies over to the SL 40.

Does anyone have any ideas?
