Lol. I said terrible, not horrible.
I put it in Diamond. They make strange choices. One of our three is a NG. integrated 345R ADS-B transponder with the feed to EFB blocked. Apparently fixable by an update, but it's not approved by Diamond. Then there's the intentionally inaccurate fuel totalizer...Thanks all. It looks like there are a few DA-40 guys hanging around. I asked because I'm running software revision 031.22 on a 2008 XLS that I'm bringing up to speed on a few g1000issues. Version 031.22 dropped the checklist, which I like, and I wondered if anyone had a copy of whichever revision brought it back. Any maintenance shop that has a Garmin authorized avionics department will install the latest software for your system and provide you with a copy. Most don't charge much for that. I may have to go that route if I can't find someone who has a copy but it won't be possible for awhile because I am getting ready to work on the mandatory fiberglass reinforcement on the rear spar. The G-1000 software is written specific to the type of G-1000 (original, NXi, etc.) but within that is configurable for aircraft specifics (CO2 detector, TCAS, etc.). There have been issues with Garmin and Diamond engaged in mutual finger pointing to avoid responsibility for creating software for legacy versions of G-1000 that integrate ADS-B and TCAS and show them both on the MFD. This aircraft is stuck behind that problem. There is a workaround but it involves adding an additional GPS antenna.
It does seem more like DIamond than Garmin @midlifeflyer because it was eventually worked out with other manufacturers.I put it in Diamond. They make strange choices.

The totalizer is fine. Works great. Same for the gauges. But in the NG, Diamond only allows you to set it at 28 even if you filled to the top. That means it will tell you you are dipping into reserves when you have 2 hours left. The inability to set it for full fuel is nonsense. I've been (and have been recommending to my checkout victims, that once both tanks show 13, reset it for accuracy.It does seem more like DIamond than Garmin @midlifeflyer because it was eventually worked out with other manufacturers.
I'm not familiar with the inaccurate totalizer issue. Which sub-model DA-40 is this? On my SN 40.876, when I pay attention to the filling level and remember to reset it at startup after filling at the tanks, my totalizer is consistently (over years) identical to what is indicated on my fill receipt within +/- 0.1 gallons. As far as the electromechanical gauges go, mine are fairly accurate too (maybe +/- 1.0 gallons, except that gap between 20 and 15 introduced by the main v. aux tanks.
I liked the checklist feature in the previous software versions. The default list was good and you could customize the text file it reads to meet your preferences.My 2008 DA40XLS (40.868) fuel totalizer works great. And I am currently running 0321.23, which equates to Garmin v12.05, released in 2013. These were the features added in .23 SW:
• MFD Vertical Profile View
• NAV Database synch capability
• Standby NAV database capability
• XM Weather Display Enhancements
• Added WAAS approach capability for airports with 3-letter identifiers
• AOPA Airport Directory Support
• Added Range-To-Altitude Arc on MFD Navigation Map
• Compatibility with Enhanced Search & Rescue Option
• Re-establishes use of checklist capability
Never tried the checklist feature, I prefer it on my iPad and CheckMate cards.
