    Garmin GTN 750 Issue - Thoughts?

    I have not gone into the startup setup menu...my avionics guy didn't think that was the issue because I have been flying this setup for two years with zero issues. Happens in flight and on the ground. I understand what you are saying about RX and TX, regardless, broadcasts on COM 1 are heard...

    Garmin GTN 750 Issue - Thoughts?

    Ryan, Thanks...you mirror my thoughts on the GTN but wanted to make sure it wasn't a setting I was missing. My Avionics tech has another 750 coming for a separate project and intends to swap that out one by one with both of mine to see if that fixes the issue. Greta input everyone, grateful.

    Garmin GTN 750 Issue - Thoughts?

    Yes, the other 750 shows "RX" next to he frequency but I have confirmed with other pilots at the airport that I am indeed transmitting on both radios at the same time.

    Garmin GTN 750 Issue - Thoughts?

    Garmin Help - Linking phone to GTN 750 with GMA-35

    And I am kicking myself, I just purchased two Bose A20's WITHOUT Bluetooth because I thought my aircraft had it (long story but I was at prebuy with a different Saratoga that had a GTN-750 and I used the bluetooth during my test flight on that aircraft). I have not yet researched an option to...

    Garmin Help - Linking phone to GTN 750 with GMA-35

    Thanks for the reply. Perhaps I should caveat my comments, I am not looking to make phone calls in flight, but I would like to make a call from the ground. To pick up an IFR clearance at my home airport you have to call approach prior to takeoff or pick it up once airborne. Also, I would...

    Garmin Help - Linking phone to GTN 750 with GMA-35

    Hello, Wonderful forum with a lot of great information. I've read through many posts but have not seen an answer to my specific question. I recently acquired a Saratoga with a very nice Garmin setup: • STEC 55X Autopilot Featuring Altitude Hold • Altitude Pre-Select with Vertical Speed...
