One thing I didn't realize that kind of bums me out is that you have to buy a $1,500 SD card (Flightstream 510) to have connectivity with ForeFlight and to get over the air database updates. I'm sure that's a known thing, but this is my first panel mounted GPS, so wasn't aware. Not sure if I'll do it or not, but seems like it would be a really useful add-on.

I have one anduse it as my second Nav or GPS source which is required in Canada for IFR. I have not used the GPS portion very much as I have a GTN-650 as my primary unit. Works well with the G3X however two dislikes I have. The GNC and GTN do not crossfill to each other. This to me is a major weakness especially if it is being used as a back up to the 650. The other thing to note is that it doesn't have a "default NAV" page like the 650 has.
I recall crossfill being discussed as a possible future update to the GNC/GNX series a few years ago.
Here’s the current GTN install manual

Perhaps this is still a possibility in the near future?
You can connect to the GNC 355 via Bluetooth without the need for a Flightstream 510.
Thanks,

Thanks Justin- so it's possible to load a flight plan from ForeFlight to the GNC 355 without the FlightStream? That would be great news! My plane went straight into annual after the install so I can't tinker with it for another week or so. I appreciate the guidance.
Yes it is. I’ve done it many times.
I am redoing my panel from old Dynon D100/120 and G5 to full 3 screen G3X and I kept the 355 rather than swap to another navigator. I replaced a 250XL and needed the comm. Starting fresh, the 375 is hard to beat if you don’t already have a ADS-B solution. I really like typing my comm frequencies rather than twisting the dial.

Do I understand correctly that you have to buy a $1,500 SD card to get database updates? I read where you can get ForeFlight to transfer your flight plan using Bluetooth so that’s good but database updates occur every 28 days.
I’ve currently got two non WAAS 430s installed and have been thinking about the 355 so an additional $1,500 data card on top of the $6,000 plus cost of the 355 could be a show stopper.
