I don't have a bluetooth headset either, and I would be reluctant buy one since I prefer to have control over the audio in one place and be able to suppress alerts at busy times with the push of a button.
So the response below, to use bluetooth from Skydemon on my ipad would not work for me. Does anyone else have this problem? Can anyone offer any other solutions, for example a standalone bluetooth to audio jack gizmo?
I was not a fan of the loss of the audio out jack on the FX.
However, there is an opportunity here for an improvement.
I used a Bluetooth receiver into my Lynx intercom, you could use the same and connect a BT receiver into your Garmin if you can source the right wiring.
The big bonus of doing this is that you can then get both traffic and airspace alerts, properly spaced out without one talking over the other.
Set both up from Skydemon, which will then transmit them over BT to your intercom.
When flying with the FX, I therefore have both traffic and airspace alerts.
The BT adaptor I bought has an on/off switch and a volume control on the body, so all alerts can be quickly adjusted or turned off.
You will need to get USB power to the adaptor...
