LANCECASPER Posted December 1, 2021 Report Posted December 1, 2021 You have to love Mooneyspace!! I thought my AHRS was going out. I kept getting this message: I found this post, dug out an old Dell Windows XP Laptop and updated it this morning and all is good!
rodrigodietric Posted April 9, 2024 Report Posted April 9, 2024 I'm with Seneca v, trying to carry out this update, but I followed your advice and couldn't, anyone to provide support?

Did you read through the entire post and look at the Garmin .pdf that was attached to @Jeff_S's November 13, 2020 post? That's what worked for me in 2021 after I bought my G1000 airplane.
Pinecone Posted April 9, 2024 Report Posted April 9, 2024 Since this thread started 4 years ago, you may have a different issue. I would call Garmin.

Eu ligaria para a Garmin. Yes, I've even spoken to Garmin and Jeppessen support, and they both sent the same PDF. But I saw from the discussions that I should turn off the CB's Com2 and Nav2/GPS2. However, in Seneca, I only found AHRS and Com2.

Since you have a Seneca, talk to a Piper Service Center that has an avionics shop. They may have a specific service bulletin. Maybe our friend @AVDB can help - he is a G1000 expert.
PaulM Posted April 9, 2024 Report Posted April 9, 2024 We would need to see a picture of the breaker panel, or have a copy of the detailed wiring diagram (the poh one is usually not enough) We would essentially be guessing which breaker handles GIA63#2. They can be separate breakers or they could be combined. from what I see in the POH there is only a COM#2 breaker. I would pull that breaker and check in the status page on the G1000 that COM2 and GPS2 are offline.

PaulM Posted April 10, 2024 Report Posted April 10, 2024 GEA(71) is the Analog-Digital Input/Output data system, not the GIA63(W) which is the NAV/COM/GPS unit.. I suspect your GIA is just labeled as COM2. boot your G1000, Pull the COM2 breaker. and look at the status of the LRU modules.. COM2 and GPS2 should be marked offline. That is "AUX" group (outer knob) then "system status" which is 5-6 clicks of the inner knob. That should list all of the LRUs..
AVDB Posted April 21, 2024 Report Posted April 21, 2024 From Diamond DA40NG wiring diagram of G1000 system which is near to me right now, and I can with a fatness of 99% also say that this is true for other G1000 equipped aircraft - GIA 63(W) is the central ‘Integrated Avionics Unit’ (IAU) to the G1000 system. The GIA 63(W) functions as a main communications hub, linking most LRUs with the PFD and MFD displays. The GIA 63(W) contains the GPS (WAAS) receiver, VHF COM/NAV receivers, and system integration microprocessors. It is powered up via two appropriate circuit breakers GPS/NAV 1(2) and COM 1(2) - GEA 71 - LRU that is responsible for receiving/processing signals from engine and airframe sensors) GEA 71 communicates directly with both GIA 63(W)s using RS-485 digital interface it is powered up via one circuit breaker - ENG INST On Seneca this C/B calls GEA, because two engine are installed, we see GEA 1 and GEA 2 C/B on circuit breaker panel. 1
Jeff_S Posted October 31 Author Report Posted October 31 Hey folks. Time's fun when you're flying...or time flies when you're having fun...or something like that. It's MagVar Update time again. I got the "Update MagVar Now" message after loading the latest database update and since I'm old, and this was five years ago, I completely forgot about the rigamarole we went through then. But of course the update failed...I never waited around long enough for a failure message per se, but it just kept sitting there doing nothing. Luckily power cycling the G1000 brought it back to normal. So I will search around to see if there are any new or different procedures for our G1000s this time. Stay tuned!
Jeff_S Posted October 31 Author Report Posted October 31 Okay, that was easy. I've attached the file to the SB that seems to be similar to last time, so if you did it before you can do it again. It does include instructions for different operating systems this time, so I'll try it like they say for my Mac. UPDATE: There is actually a Mac-specific link which just downloads all the files into a folder so you can easily transfer them to an SD card. That was nice. Here's the link as well, if you want it: https://atlaske-content.garmin.com/filestorage//email/outbound/attachments/25056A_Time1759762392942.pdf I sure hope MooneySpace is around five years from now when we have to do this all again!

PaulM Posted October 31 Report Posted October 31 If you have upgraded to the 401.37 software, then the regular upgrade works directly in the MFD. It will just tell you after the splash page to authorize the update.

I updated my chart and nav data DB's yesterday and was surprised by this magnetic variation model update. I stared at it for a while and then selected Yes since why not? It didn't complain. I read the SB later at home and wondered if I'd missed a failure. Knowing that the update process now works in the later revs makes a lot of sense. Does anyone know of a quick way to check the magnetic field model in use? (legacy G1000 here, at the .37 rev from memory)

LANCECASPER Posted November 1 Report Posted November 1 I updated my databases today and it took about 5 seconds to update the Mag/Var database.
Jeff_S Posted November 1 Author Report Posted November 1 Good to know the latest SW version smooths the process. I can't remember why I haven't done that upgrade. What features did it have? And does that have to be done by an MSC or can an avionics shop do it?

Just did the update with 0401.37. Went as smooth as @LANCECASPER reported above. After updating the NavData of PFD and MFD the dialog is presented on the MFD. After confirming with OK the mag var database in the AHRS gets updated. When completed the AHRS reinitializes „Keep Wings Level”. Done.

You buy the 401.37 software through an MSC. - - - - - Also now a few G1000 owners have added an Flight Stream 210 to be able to transfer flight plans via Bluetooth, which is only possible with 401.37.
Alan Maurer Posted November 2 Report Posted November 2 Mooney People, I admit that I don't understand any of this. The same stuff popped up on my G1000 MFD. I thought something was broken. I have no idea what this is for or how to use it. We only have Mac stuff here, so clueless. What does this thing do and is it worth anything__ Thanks Alan

So if yours is updated as mine was, should be a non issue. HTH David
Jeff_S Posted November 3 Author Report Posted November 3 @Alan Maurer, it seems you will have one of two experiences, depending on what version of the G1000 software you are on. If you have the latest version 0401.37, then you can select to update the magnetic variation database that came with the latest nav-data updates and all will be hunky dory. If you have version 0401.34 (and perhaps earlier, non-WAAS versions) of the software then if you try to update the mag-var data from the dialogue box you will get into a loop that requires you to shut down and start up again. If the latter happens to you, then you'll need to follow the procedure outlined in the SB that I posted above. HOWEVER: I have to report now that when I ran this procedure on my Ovation, even though the system said it had successfully upgraded the mag-var data, when I started up again I am still getting the dialogue box on the MFD asking if I want to update the data. So something seems amiss. I have a case in with Garmin to get this figured out. I'll post here when I have it resolved.
Jeff_S Posted November 4 Author Report Posted November 4 As an update, I hate being some company's software tester but it appears this happened again with Garmin. I jumped right on the file download as soon as I heard about it, and when I ran through the procedure it kept telling me I had successfully installed the 2020 data! Which of course meant that the update didn't work and I kept getting the "Update MagVar data?" message when I booted the system. Spoke to Garmin this morning and they confirmed they hadn't actually put the correct files in the link that is found in the Service Advisory, and that I should try again. So I downloaded the new file set and it does seem like the two "igrf..." files are newer, created on October 29 compared to those files from before having been created on October 1. So I will try again tomorrow and report on the results. Those of you who waited a bit to download the files probably had no issues!
