Any hope for a GFC500 for Cessna T210-R. This is the only model without an STC

Mark Russell — Wed, 10 Dec 2025 16:31:46 GMT

Title says it all. Are the owners of 1985-1986 T210s without hope for the GFC500?

Hi George, sure it'd be great to discuss. I am currently using an STEC 55x, but I have full Garming glass. I looked into the Stec 3100, but Genysis just sold the product line to a new company and their customer service doesnt seem to be up to speed yet. I made a dispoable email for you to contact me at: gfc500mark.am71m@simplelogin.com

Hi Mark,

I've been trying to get a Garmin AP for T210R too. I’d like to ask you a couple of questions/discuss it further outside the thread if you’re open to it. I can’t seem to message you through the forum. Is there a preferred way to contact you?

Regards,
George

Concierge to update GTN navigation database through GI275 (GTN database only)

8820933 — Sat, 16 May 2026 15:16:05 GMT

I have a GTN 750XI and dual GI 275s. I only need an active Nav database subscription for my GTN 750 XI. I am able to use concierge on Garmin Pilot to update the Nav database on my GTN 750 XI using GI 275 wireless interface? Implicit in the question is that I understand the Nav datbase in teh GI 275s woudl be out of date.

Garmin G5 + GAD 13+ Davtron C307PS

6748734 — Sun, 05 Apr 2026 13:02:15 GMT

Hello,

I recently installed a Garmin G5.
I’ve also fitted a GAD13 and a Davtron C307PS for the OAT.

Everything was installed correctly according to the fitting instructions, but the G5 isn’t displaying the OAT.

I’ve attached a few photos below.
I don’t own any other Garmin devices, so the existing CAN cable would need to be disconnected.

Best regards

I have installed a standalone G5 system including the GAD13/C307PS combination in my aircraft and it has always worked without any problems for me.

The G5 does not communicate with the GAD13 using RS-232. If there are no other third-party devices interfaced with the G5, both the input and output format on the "RS-232 Configuration" page should be set to "None."

Try looking at the "Device Information" page in configuration mode. If the GAD13 does not appear in the list with a green tick next to it, then there is probably a problem somewhere with the wiring for either the Garmin CAN bus or the GAD13 power.

Anybody else seeing database subscription weirdness lately?

4356979 — Sun, 20 Jul 2025 00:51:06 GMT

My "US VFR Plus Database Bundle" (the $50/year sub) seems to have just spontaneously disappeared.

The last databases in my G3X Touch expired just a week ago, but when I go to GADM it says I have no subscription and no databases.

When I log onto the Garmin site, it thinks my last sub expired in May of 2024 (!). Yet I was getting databases as recently as a a month ago, and I was on auto-renew. There's no sign of that on Garmin's web site - as if I never had it (at least since 2024).

I did a chat with support and they just gave me a 1 year IFR subscription for free to stop my complaints, but without any explanation as to what happened.

That's nice and appreciated, but am I the only one whose sub just went poof?

GNC420 Database Card

I have a GNC420 with a bad terrain/obstacle data card. Anyone know where I can get a replacement that will work with a Garmin Card Reader and associated Database?

thanks

How do i connect android version of GP to a stratux?

1243416 — Thu, 23 Apr 2026 01:36:29 GMT

I don't have a gdl90 option in devices and picking any option wants to connect via Bluetooth. What am I missing?

RE: Anybody else seeing database subscription weirdness lately?

9101853 — Mon, 13 Apr 2026 19:43:38 GMT

I just had similar thing happen. My databases autorenewed in Feb, but Aviation DB Manager shows no subscription so I can't download/update. I have reinstalled AvDB manager and that didn't fix it.

It's easy to say "give our support a call", but I'm currently on hold for that and it says an hour and a half! That's not reasonable.

RE: Loading approach after destination

John G — Sat, 14 Mar 2026 17:03:38 GMT

I finally had a chance to try this yesterday. I had entered a simple flight plan, E14-KLAM. When I activated the approach to KLAM, the flight plan disappeared and all that showed was the the approach waypoints, no destination. And perhaps because E14 is not far from KLAM, the 175 took me direct to the FAF, not the IAF as usual.

Loading approach after destination

John G — Mon, 23 Feb 2026 23:50:30 GMT

When I enter a flight plan in the GPS 175 and select/load an approach, the approach is loaded after the destination airport. How do I make the approach appear before the destination?

RE: terrain data card for GNS won't update

6419339 — Thu, 12 Mar 2026 02:41:37 GMT

I have two sets of cards for my GNS 530W, and the TERRAIN on one card just stopped working. I am still able to update the OBSTACLES on this card, although my last attempt gave me an error after receiving the success notification that "An issue occurred notifying flyGarmin about this update/installation". The link above to the GNS repair tool takes you to an empty Box folder

terrain data card for GNS won't update

9355407 — Thu, 05 Sep 2024 14:19:02 GMT

I have 2 TAWS/terrain data cards for my GNS 430W. Today, I tried to update the obstacle database, and Garmin Database Manager won't recognize the cards-- the yellow light is on the programmer, and the card name flashes briefly on the screen repeatedly for both cards. iwas able to easily update my navigation data card. I have seen discussions on other forums of a data card repair utility for terrain cards. Where can I find this?

RE: Loading approach after destination

Garmin-ZM — Thu, 05 Mar 2026 17:13:16 GMT

Hello,

When you load an approach, you will want to activate it in order for it to appear before the destination airport. If you load the approach then it will appear after the destination airport. I hope this helps!

SouthPAN SBAS Compatibility

Vulpis Caelus — Sat, 17 Jan 2026 23:47:00 GMT

The SouthPAN GNSS augmentation service (SBAS) covering Australia and NZ is currently planned to be certified for safety-of-life applications in 2028. Is there any way of knowing which models of Garmin's WAAS aviation receivers will properly support SouthPAN once it becomes available? I expect that any current models would work just fine, but I haven't been able to find any definitive information on the Garmin website.
If some sort of enablement is required, would it also be available on Garmin's legacy products, eg. 400W/500W series or GNS480/CX80?
Would standalone position sources used for ADS-B, eg. GPS20A or GTX345 need a firmware update?

RE: GFC 500 will not enter NAV mode for GPS track

Garmin-NG — Thu, 08 Jan 2026 16:19:28 GMT

Hi Bryan! Thank you for being patient while we upgrade our forums. Excellent job providing photos! After reviewing your photos, I noticed your GFC 500 does not indicate AP is on nor NAV mode being selected. This could definitely result in your autopilot not functioning as you're expecting it to. Try doing so the next time you fly, and if the issue is still present, please contact your installer of the autopilot for further troubleshooting, as it might require some further examination.

GFC 500 will not enter NAV mode for GPS track

bryanwhitmarsh — Tue, 08 Apr 2025 02:14:36 GMT

I can’t get NAV mode to work for a GPS track. It will work when tracking to a VOR. This used to work, but I’m new to the setup so may be something simple I’m doing wrong. HDG and TRK mode works just fine. Can anyone see what I’m doing wrong? Thanks

GTN 750 Import Flightplan from Skydemon

2292389 — Thu, 01 May 2025 14:53:54 GMT

Hi folks,

the C172 which I charter has a build-in GTN750

I personally use skydemon for planing.

I know that it´s possible to import the created flightplans into the GTN750 (not XI)

For that, you shoud export the flightplan in Skydemon to the root of an SD-Card.

I tried both, the original database SD-Card from Garmin an empty on.

The you should insert the SD-CArd, power up the 750, hit the "flightplan" butten, then menu, the catalog, then menu again and there should be an "Import" Button, but in my case, there are just the "delete all" and the "delete pending" buttons.

Where is my error?

Main Software Version is 6.73

GPS Software 8.3

Com Software 2.30

NAV Software 6.03

Any solutions?

Regerads and happy landings

André

GNX 375 unit failure

5227947 — Thu, 04 Dec 2025 03:08:43 GMT

Has anyone had any problems with a GNX 375 that was installed in late 2025 having power failure issues? I had an airplane leave the shop and had flown for a little over 5 hours (multiple flights) and had a screen blackout on them while taxing back to parking. Then the screen would try to reboot but kept blacking out like a boot error would.

Has anyone else experienced this phenomenon? [View:/cfs-file/__key/communityserver-discussions-components-files/942/IMG_5F00_5107.MOV:320:240]
