Re: Garmin G-1000 ADS-B solution?
Ken, I am confused. Is there a new antenna on the outside of the plane, or the internal fuselage? I currently don't have any GDL69 antenna on the outside of my plane, it is hidden somewhere inside the structure.

We had to install the GTX345R with GPS and a new GPS antenna. We chose to replaced the #1 GIA63 com antenna with a dual GPS/comm antenna.

Re: Garmin G-1000 ADS-B solution?
so the stick radio antenna on top got replaced with the flat gps style antenna? That sounds convenient enough. If possible, a picture of the result would be awesome!

Here's the antenna the was installed. I'll try to get to the hangar tomorrow or Saturday and get some pics.

Hi Ken:
Two questions on the install of the GTX345R with GPS and a new GPS antenna.
1. How many hours of labor did it cost you.
2. Do you use ForeFlight on a ipad and are you able to connect wireless to the GTX345R to get weather, traffic and attitude on your tablet as Garmin advertises?

Re: Garmin G-1000 ADS-B solution?
FWIW, my take-away from extensive discussions with both Garmin & Diamond at OSH is that the "elegant" GTX345R solution for WAAS DA40s is at least a year away (if ever). A major complicating factor is that Garmin currently owns the G1000/DA40 STC (AFAIK, unique for all G1000 aircraft), and responsibility will likely shift to Diamond at some not-yet-agreed-to point.
The fluid STC ownership situation doesn't provide Garmin incentives to make this a high priority, and Diamond can't solve the problem without Garmin's assistance or STC ownership. So we are left holding the bag.
Overall, Garmin was particularly (if typically) unhelpful about future plans. They also didn't seem fazed that the GTX345 marketing left out crucial details only found deep in the installation guide.
More generally, while G1000 functionality is fantastic, the longer-term future is really unclear. Tying avionics (by definition, eventually obsolete) to the type certificate seems like an eventual train wreck.

Re: Garmin G-1000 ADS-B solution?
Just to reinforce the points that Chris made above (he spent considerable time talking to both Garmin and Diamond while attending AirVenture Oshkosh last week; I also talked with Diamond about the ADS-B issue at AirVenture), here's my understanding of the latest situation for DA40 owners who want to install the GTX345R for ADS-B:
Owners of WAAS-equipped DA40s (typically 2008 or newer XLS models) cannot install the $5000 GTX345R that utilizes the plane's built-in WAAS position source. This would require new G1000 software (including GDU version 13, beyond GDU version 12 included in the current .23 G1000 software) that doesn't exist, nor is such software currently under development. Garmin (who owns the STC for the DA40-180 G1000, since the DA40 was originally certified by Diamond as a steam-gauge aircraft) has no interest in developing this software with everything else Garmin is working on right now.
To address this issue and provide better long-term support for Lycoming DA40s, Diamond Canada intends to take possession of the Lycoming DA40-180 aircraft Type Certificate from Diamond Austria. Once this change in TC ownership occurs, Diamond Canada can then acquire the G1000 STC for the DA40-180 from Garmin and request G1000 software updates. This process will take time, which is why (as Chris noted above) it will be at least a year before owners can expect new G1000 software beyond .23 for WAAS-equiped DA40s. These steps will better let Diamond Canada control their own destiny with regard to any and all future Lycoming DA40 upgrades -- not just those related to the Garmin G1000.
Right now, WAAS-equipped DA40 owners have the same ADS-B solution available as other DA40 G1000 owners: install the $5800 GTX345R that includes its own integral WAAS position source, along with a third GPS antenna. This can be a separate third antenna mounted on the outside of the fuselage, shared use of the GDL69A XM satellite antenna, or (as described above) replacement of one of the VHF comm antennas with a dual GPS/comm antenna. The version of the GTX345R with integral WAAS position source is not dependent on G1000 software version because it is configured by the installing technician via laptop software with attached cable.
The DA40 isn't the only G1000 aircraft affected by G1000 STCs and software; Cessna 172/182 owners are in the same situation (where the G1000 was added via Garmin STC) and thus only the GTX345R with an integral WAAS position source and 3rd antenna can be installed for these planes.

Re: Garmin G-1000 ADS-B solution?
Although this doesn't affect me directly, I raise this (perhaps stupid) question:
If the GTX345R can not interface with the G1000, how does one set squawk codes, ident, etc. in the 345R? Is this not currently done with the GTX33 from the G1000?

Re: Garmin G-1000 ADS-B solution?
The GTX345R transponder does interface with the G1000; the current G1000 software for the DA40 just doesn't support all of the requisite functionality needed for the GTX345R to utilize the integral WAAS GPS of the G1000.Rich wrote:Although this doesn't affect me directly, I raise this (perhaps stupid) question:

So setting squawk codes, ident, etc. works the same as today's G1000 with the GTX33 transponder.
