Navigator recommendations?

[Bdflies]

Hi folks,
I am the proud new owner of an RV-14a with an AFS 5600, Dynon com, transponder, audio panel and autopilot. I’m more used to Garmin stuff, but I’m growing fond of the 5600. In the G3X, Vnav descent profiles were easy and intuitive. I’m working on doing that, but I’m not there yet….
To the point of the post; I want to install an IFR navigator with a com. Is Avidyne preferred? Or does Garmin play nice with the AFS stuff? I’ve been looking at the Garmin 355, but haven’t seen it mentioned with regard to AFS. I’m wanting to move forward, but not in a rush. Cost is less important than compatibility and functionality.
Just wanting to hear from those who’ve gone before me.

Thanks,

Bill
