Steve, Im debating between the Gnx375 as a part of my planned G3X panel like the Garmin panel or sticking with the originally planned GTN650 (with Gtx 45r)
Advantages to the GNX :
Cheaper by about 4k
Lighter by a few pounds
Less power draw
Advantages to GTN :
ILS/NAV capabilities
Integrated panel COM
Assuming I wouldn?t miss the NAV function any thoughts on this decision? What you really need to offer is an updated GTN with an integrated ADSB In/Out.
Hello Rob,
As you can imagine, we get this question a lot via our G3Xpert inbox. We appreciate that many are struggling with this decision.
To start off, lets compare some pricing. I went online and found the following approximate street prices:
GTN 650 $10K
GTX 45R $3.5K
Total $13.5K for GPS/NAV/COM plus 1090ES ADS-B In/Out
GNX 375 $7K
GTR 200 $1.2K
Total $8.2K for GPS with 1090ES ADS-B In/Out plus COM
Agree that the large difference (besides saving $5.3K) is loss of VOR/ILS, but you also lose some of the premium features of the GTN like 3D flight planning with coupled VNAV.
Everyone has to decide what is important to them. To some, not having a NAV radio is a show stopper, but to many, they no longer use VOR, and no longer need to use ILS since LPV is way more available than ILS, especially in the smaller airports that many homebuilts prefer.
I like to tell people that the small airport where I am based with a single 3400' paved runway has no VOR/ILS approaches, but has awesome LPV approaches into each end of the single runway.
I have a GNX 375 and a GTR 200 in my homebuilt and absolutely love using them both and feel like they are the best fit for my needs and preferences, but no doubt I would also like a GTN 650.
The size, weight, cost, power consumption, and capabilities of the GNX 375 make it a really good choice for a lot of people.
Good luck with your decision!
Thanks,
Steve
