Hi John,

There are several threads about GTX3x5R installation.

viewtopic.php?f=8&t=6226
viewtopic.php?f=8&t=7099


From what I saw from the other owners' report, the ballpark for 345R is $9,000 ~ $12,000. So 335R should be bit lower.
I installed 345R for $12K, which seemed to be higher than the others. (nothing special in the installation, but the quote was simply higher)

This is one option (although not the cheapest):

It does have the advantage of approved data (it is covered by a Diamond Service bulletin).

Garmin quotes $5,000 for the 345R. Did you have to pay more than $5,000 (e.g., the internal GPS model is $6,000) or was there $7,000 in labor?

Hi Russ,

Parts $6,500 (GTX345R and Comant GPS/XM antenna)
Labor $5,200 (flat rate)
Total about $12k (incl. tax)

I believe they finished in 3~4 days, so labor $5,200 was too high. But it was a flat rate. :(


@John
I don't know anybody installed the antenna in the front panel or tailcone.
Mine is in the aft fuselage where XM antenna was installed.

Hey John, you are not located terribly far from me (2 hour flight). In November I had installed the GTX-345R with internal WAAS, and a GPS/XM dual antenna (replaced existing similar looking antenna on top of fuselage) all for $9300 from Ron Collins located at KEHR in Kentucky. They did a great job, no problems, took a solid week. The new transponder comes with the encoder. The GTX33 is completely removed. I’ve found $9K is the norm for the 345 install with internal GPS. The 345 is $1k more than the 335, and I personally think its worth every penny. The traffic on the MFD (and PFD inset) is spectacular. I think Collins is currently booking into June. I was the 4th or 5th DA40 they’ve done.

I don't remember the specific details on the "shelf" but IIRC, for my GTX345 install they said they installed a GPS antenna in the position that the GDL69 antenna would've been and it seemed to be a straightforward process. (I do not have the GDL69) I think they said that if it does have the GDL69 antenna, it could be swapped out for a combo XM/GPS antenna.
